Know your magnets polarities

[@Tibouchina11]

FINALLY!! Someone who can explain and show us how to find the North side of a magnet. I have been so confused about this topic and the way that you showed how it works was so helpful. Thanks so much. Really....

[@brainiac75]

@IroniMan100 : Thanks for watching and subscribing! I will make more magnet videos - maybe not soon but they will come :o)

[@brainiac75]

Thank you for watching and commenting :) You're right. Nature doesn't care about north/south. It's a convention that we humans have decided to apply to nature. And by our definition the pole on a loose magnet pointing close to the geographic north is the north pole on the magnet. Therefore the magnetic pole of the Earth near the geographic north pole is the magnetic south pole of the Earth. That's rather confusing and I didn't want to include it in the video :)

[@rajendrasathe8637]

You comment that the north and south poles are conventional we humans have decided north and south pole. But I have learned that the magnetic lines of force goes from north to south outside magnet and south to north inside the magnet. Is this also conventional. And can we determine polarity of magnet without using any reference. Thanks for your explantion.

[@brainiac75]

It is something that we humans have decided to have a common standard. Nature doesn't know of north and south - it's just our convention :) Thanks for watching and commenting!

[@jackraves7363]

🙏 the session-part where you use the compass are the most important for me… thank you! Learning all the time I am ☺️

[@brianbrewster6532]

Thank you for publishing this highly useful tutorial. You inspired me to purchase an orienteering compass I fully intend to use on my next camping adventure. But for now, I really need this compass so I may mark the N & S poles of these expensive Neodymium cube magnets I recently purchased. You rock!

[@patrickzavas]

compasses point to the south pole of a magnet. This is because compasses are made to point to magnetic south, and the geographic North Pole  coincides with the south magnetic pole  of the Earth. The north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic north pole.

[@sliderulelover]

Excellent tutorial on finding North and South poles of a magnet. Well done!

[@TechnologistLive]

Backwards...

[@bobskie321]

Because opposite polarity attracts (1:07) which means that the north earth magnetic field which the north needle of the magnetic compass points is actually south because the surface of your magnet which you marked as "N" (north) is attracted to the south portion of the magnetic compass (1:16).

[@GrantsPassTVRepair]

Since the earths geographic north is magnetically south, do you happen to know which description is used when someone describes the polls of a magnet?

[@Pnutty9037]

The convention in early compasses was to call the end of the needle pointing to the Earth's North Magnetic Pole the "north pole" (or "north-seeking pole") and the other end the "south pole" (the names are often abbreviated to "N" and "S"). Because opposite poles attract, this definition means that the Earth's North Magnetic Pole is actually a magnetic south pole and the Earth's South Magnetic Pole is a magnetic north pole.[5][6] The direction of magnetic field lines are defined to emerge from the magnet's north pole and enter the magnet's south pole.

[@ratedxxxable]

Peanut! You are absolutely correct and luckily l read your comment and it saved me from writing virtually the same factual information. It certainly is refreshing to see others who have a knowledge that is greater than most on a subject that everyone should be aware of with a superior understanding​ and knowledge of.

Thank you Peanut! You too steve russell:)

[@jeffreycarter4240]

s Excellent tutorial on finding North and South poles of a magnet. I have spent hours trying to get alternator to work with out knowing which way the permanent mags are pointing. Well done!

[@gezondwereldnieuws6836]

Wow the best video...... thanks for sharing. FINALLY!! Someone who can explain and show us how to find the North side of a magnet

[@youGooglin]

If the magnet attracts the north, wouldn't that be the south pole of the magnet attracting it & the north pole of the magnet would repel the north pole of the earth?

[@LionelDerenoncourt]

I am eighty one years old and I never know how to recognize the poles, you teach me that so well that I am very happy now

[@chbonnici]

Your presentation is nicely done. Your Danish accent is great. Thank you

[@brainiac75]

Charles Bonnici Thanks for watching and commenting :)

[@mikesnitro]

Thanks for posting. I have magnets of different shapes and had fun with the compass.

[@giuliobuccini208]

Actually, the geographical north-pole correspond to the magnetic south-pole of the earth. So the "north" needle on the compass is pointing to the right direction (the geographical north) just because opposite poles attracts each other.

[@wowzers9270]

Pleasant music and voice! Thanks! I like method 3 as it is the most basic, fundamental and origin.

[@brainiac75]

@LJnandSrada : By definition the northpole of a magnet is the pole of the magnet that points towards the geographic north. The reason for confusion could be that the Earth is a magnet in itself (thats why compasses work). And the Earth's magnetic southpole must be at the geographic northpole since our magnets point the northpole at the geographic northpole which is magnetic southpole... Confusing yes, but a loose magnet will point its northpole against north. That's all you need to know.

[@brainiac75]

Thanks - more videos with magnets coming up :) I don't have magnets from CD and DVD units but I guess they are similar to the ones in hard disk drives that I have quite a lot of. These are multipole magnets and have both a north and south pole on each flat surface (4 poles). I think they magnetize them in this way to keep the magnetic field very close to the magnet so it doesn't erase the info on the HDD-platters :) So yes - it is possible to have both a south and north pole on the same surface.

[@patrickzavas]

It's interesting how the South Pole of the planet is actually the magnetic North Pole. Or is the compass marked wrong...? If the compass is marked wrong then that's the South Pole of your magnet. If what we call the South Pole is actually the magnetic North Pole of the planet then that's just shenanigans.

[@brainiac75]

That could work but as you point out in your comment it is easy to get north and south mixed up on an electromagnet. The north pole of the electromagnet is determined by using your right hand. Wrap your fingers around the coil in the same direction as the current is flowing (the 'conventional current flow' from + to -). The direction your thumb is pointing is the direction of the magnetic field, so north would come out of the electromagnet in the direction of your thumb.

[@SuperMagnetizer]

Excellent videos (all of them!) The Earth is a giant magnet. The North-seeking Pole of any magnet appears to "seek" Geographic North, but is actually attracted to Magnetic South, which is near the Earth's Geographic North Pole. Likewise, the Earth's Magnetic North Pole is near the Geographic South Pole.

[@williambiggs3699]

So, I'm still a little confused. If I wrap a wire around a nail so that it resembles a regular screw💈. If I attach the top wire to the positive end of battery which end would be north, top or bottom?

[@brainiac75]

Glad that I could help! The topic can be very confusing (just look at some of the other comments to this video...)

[@MagnetTricks]

Nice job as always! The compass method is twisting my head. The white part of the compass needle points towards the south pole so you would think there is a northpole magnet at the end of it because opposites attract, right? But what you are actually saying is that the compass needles southpole magnet is pointing towards southpole. I don't get this, what am I missing here? I tried the floating magnet method and I came to the same conclusion: the northpole of the magnet is pointing towards north? Also we did a interesting magnetic experiment on 2 different hemispheres where I stumbled into this same phenomena. Is it just that the pole on the northern hemisphere what we call north pole is actually magnetic south? Please enlighten me.

[@brainiac75]

+Cobrakiller2000 You have figured it out yourself: the magnetic south pole of Earth is located near the geographical north pole. When the north pole of a magnet points in the direction of geographical north it is because the magnetic south pole is located up there - opposites attract :) Thanks for watching.

[@McNea1234]

+Cobrakiller2000 The Geographical north pole is actually a magnetic south pole, therefore the Northern arm on a compass will be attracted to geographical north.....not due to the polarity of the compass itself but rather the difference in geographical north actually being the magnetic south. I said it twice but meh :P

[@MagnetTricks]

Lucas McNea Yes I figured it out eventually. needlessly confusing. Somebody in a survival situation trying to figure out compass points with a magnet could end up going to the wrong direction without this knowledge :)

[@rich1051414]

Its because the pole of a magnet was named after the direction of attraction, before magnets were really understood. Now, try learning about electrical polarity and electron flow vs conventional current LOL.

[@goretoye]

you saved me a headache trying to figure out the North Pole. Thanks!!

[@boatbyrd]

I am so relieved that so many others were experiencing the same confusion as me. My first question was, on the compass needle, does the needle contain a magnet, with the south pole magnet on the "red" north end, and the north polarity magnet on the south (white) end???This would clarify everything. If I dont get a reply soon, I will just deconstruct my daughters cheap compass to find out! :) Ken Byrd

[@paganphil100]

boatbyrd: Yes you're correct......the South pole of the needle (usually red or orange) is attracted to the North pole of the earth because opposites attract.

[@tomascancelliere4348]

Interesting, could the cube have 3 potential north south manetic axis? Will the compass react if the magnet cube is on the table is diametrically oriented to the compass? Also hanging a magnet will orient to a north south axis of course but maybe not which is which without looking at the sun? I am not trying to nit-pick your video, these are serious questions with the utmost respect to you and your channel.

[@MaestroRigale]

Your content is really interesting. Your voice is also very soothing, as are your background music choices.

[@brainiac75]

Thanks :) Much more to come in the same style.

[@jeffgrave]

Thanks for this great demo. I was pointing my disc magnets incorrectly to relieve my toe arthritis pain, they need to have north facing the body, your video allowed me to measure them correctly.

[@brainiac75]

You shouldn't wrap your fingers in the direction of the winding. You should wrap your fingers in the direction that the current flows in the windings. Therefore a polarity change will also change how you hold your hand and which way your thumb points. So the poles do switch side when the polarity is switched and the rule of thumb works :)

[@PamelaB1212]

Thank you so much for this video ‼️👍🏼😀

[@chinoreyes5611]

I am confused. Aren't the hands of the compass opposite from the poles it attracts (e.g., the North Red hand has a polarity of the south while the South white hand has a polarity of the north)? Doesn't this mean that the side of the magnet that attracts the South White hand is actually south?

[@josesstuffcosasdejose2748]

Exactly what I needed, great tut. thanks.

[@saltpepperketchup7082]

But if you don't know which way is north, and you don't know which end of magnet is north, could you possibly head south accidently if all you have is a magnet to point?

[@stxejn]

When hanging the magnets by the string, how could you tell the magnets were attracting to the north section. Basically how could you tell the proper direction?

[@tushar3613]

Can anyone explain ...why torroid do not have poles whereas the circular hollow magnets have poles?

[@kamaljadidyaval9015]

Nice idea about the sphere

[@JonasErmino]

You should've added that the magnetic north pole is actually located in the geographic south pole and vice versa. It's just another way of saying it but that part at 4:10 got me a little confused lol (maybe it's just me tho). in any case, great vid!

[@RobertShaverOfAustin]

I love your magnet videos. Thanks for making them. If I understood correctly, you said that the pole of a magnet that is attracted to Earth north is marked North. Since opposite poles attract that means that the Earth north pole is actually South. Right? I think I've heard this before and I see why that convention is followed, it's just a bit confusing to think about.

[@johnmorrison4224]

Humans created direction before they knew about magnetism. Scientists are very reluctant to change information they have spent their lives on. Cosmologist are the worst.

[@JerryDechant]

Thanks! This video was very helpful and easy to understand.

[@drinski6720]

Could you explain that magnetic north pole of compass show magnetic south pole of the Earth wich is at the geographic north of the Earth ?

[@smitty8978]

This is amazing!

[@MrKalvinC]

Please could you do a video for me? I don't understand the energy of magnets - where does this quite substantial energy come from and why has it not been able to create a perpetual motion machine? Sorry if this sounds simplistic, I am very curious though.

[@gristlevonraben]

Ken wheeler at youtube channel Theoria Apophasis has a series of magnetism videos that go into great detail. Start with video 9 in the series.

[@daviddmf]

Thanks for this. I followed your instructions for the magnets but it is not clear to me which way you point the magnets. Is north south aligned to the flow? or south/north axis aligned to direction of flow? great work!

[@manjumolb6907]

Very nice, very helpful

[@brainiac75]

Hmm. A neodymium magnet will not be demagnetized just by running current through it (the current will just go through the nickel coating). You need a very powerful electromagnet/coil with opposite poles to demagnetize a neo magnet. It is much easier to just heat the magnet - that will demagnetize the magnet. I can't think of an invention where expensive magnets needs to be demagnetized. Are you sure you don't want to use an electromagnet that can just be turned on and off by a switch?

[@marsangeles6210]

Soo the vacuum is a north pole and the force is the south pole... Any idea pls...

[@carlordena]

Is it possible to have a north pole at the center of a circular plate magnet?

[@MissGreyBlueEyes]

Hello, You seem like a magnet expert. I have a question. I found out that there is an easy way to determine polarities of a magnet only with a needle and a thread. Please correct me I am wrong! So if I lay a magnet on a table with pole facing up and If I hold a needle in a thread hanging from obove towards the magnet it will be strongly atrrackt on one side of the magnet and it would be strongly repel the needle on the other side. So strongly that the tip of needle would be pointing up. So which side is which side of the magnet then?? Hope you can help. Greetings from Norway;)

[@brainiac75]

+MissGreyBlueEyes Hi, you can't determine the polarities of a magnet that way, unless you know the polarities of the needle. The needle is magnetized by the magnet and therefore acts as a magnet in itself. But since you don't know the poles of the magnet or the needle, you can't tell north from south poles on either. If the needle is heavily magnetized you may be able to suspend it horizontally on the middle in a thread - away from the magnet - and let the needle act like a compass needle. One point of the needle should point towards the geographic north pole. This is the magnetic north pole of the needle which is repelled by the north pole on the magnet and attracted towards the south pole of the magnet. But don't let the needle get to close to the magnet. It may just remagnetize the needle and reverse the poles giving you false readings :) Hope it makes sense and helps you.

[@MissGreyBlueEyes]

+Brainiac75 thank you, it totaly makes sence. But can you explane why North side of a magnet is called negative side??

[@brainiac75]

MissGreyBlueEyes No? Positive and negative is used to describe an electric charge. Magnetism is (always) described with north/south pole.

[@t.h.o.r.]

Sorry Brainiac- the magnet will NOT point to the geographic north pole. 4:13 It will point to magnetic north

[@jt9824]

My question is about the sphered magnet. It was made by humans Right? 1st, do you mind explaining to us, how sphere magnets are made?, them how the negative and positive poles are added to it? and last. Lets assume that a magnet is created with the following materials iron and nickel alloy all over around it, then how it is possible that it is polarized with 2 different poles? I am assuming that they have one half already polarized to north and the other one to south or negative, positive, and later they glue it together. Right?

[@brainiac75]

Thanks! Yes, but I didn't want to overcomplicate this video. Unless you live very close to or between the magnetic and geographic north pole it makes no difference at all :)

[@om77bz]

very clear ... excellent !!

[@LJnandSrada]

This is very good. Thanks. I have a question, though. I'm searching for which side of a magnet is north and which is south. I have come upon answers that say the north of a magnet points south (some of these sources are authoritative-looking) instead of pointing north. If you know why there are opposing opinions will you please tell me? I'm confused at this point. Thanks.

[@Ricopolico]

Well done!

[@brainiac75]

Thanks for watching :)

[@slapnut892]

Got a question: I am trying to construct an invention with the use of magnets and I was told I could kill the magnetic charge by running a currant through it. How do I do that?

[@williamroden8495]

My science teacher was also the (American style) 🏈 coach, so he wasn't all that interested in science. Just a lot of boring textbook reading. It would have been great to have someone like you that really enjoys what you're doing and presents it in a way that makes others involved even though the videos are made and viewed individually. Your talent goes far beyond science my friend.

[@brainiac75]

Thank you very much :) Much more to come.

[@williamroden8495]

Brainiac75 . You are truly welcome. I very much look forward to your videos!

[@Texsoroban]

did using your compass to find the poles of your magnets screw your compass up?

[@brainiac75]

No, I kept the compass at a distance and only tested one magnet at a time. Otherwise you can end up demagnetizing or even reversing the polarity on the compass needle : /

[@Ic_truth]

When the compass is pointing north the side facing the compass south?

[@Medinalegend]

I have problem, I can't direction the north in my room, its give me different north !

[@ppskg1]

Thanks Brainiac75.Awesome video.

[@brainiac75]

You are confusing geographic north with magnetic north. The north pole on a loose magnet points towards the geographic north. That's all you need to know to determine poles on your magnet. (The confusing part is that the south pole of the magnetic field of the Earth ('the Earth's magnet') is near the geographic north, so the north pole on your magnet is pointing towards the magnetic south pole of Earth which is placed near the geographic north pole...)

[@1GREECE1AKHF]

I have never even touched a magnet but still your vids are interesting.

[@markovelikonja3186]

So how do you know that south of Earth magnet is on the geographic north? Is that just an agreement or is any scientific explanation behind? Thanks for your answer.

[@wayanjaya7825]

A bit confusing when you claim the north pole (-) of a magnet will point toward the geographic north pole (-) of the earth. Should not the north pole of the magnet point toward the geographic south pole of the earth? The north pole of any magnet is always south seeking. Please clarify.

[@brainiac75]

You are confusing the Earth's geographic poles with its magnetic poles. They are not the same. The convention is that the magnetic north pole of a magnet points towards the geographic north pole. But that means that the Earth's magnetic south pole is on the geographic north pole since magnetic north is attracted to the magnetic south :) Yes, it is confusing but all you need to remember is: a magnet's north pole will point north. Thanks for watching!

[@TheSmokingGun57]

brainiac75 No... that is confused....I had this question and confused the crap out of me when contemplating this until I went to a "knowledgeable" authority** which determined that a compass' N pole...the one MARKED N is actually indicating it is North SEEKING, and it is the COMPASS that is reverse marked or misunderstood and deceptively labeled, because when the N of a compass points to a magnet it is pointing to the N pole of that magnet, and the S of a compass pointing to the south pole of a magnet, Or else people following a compass would end up going the opposite direction than intended if the north pole on a compass wasn't magnetized to being South poled so that it will POINT North always, and does NOT "align" with the magnetic lines of flux as some seem to think, but instead are simply marked to tell people simply which direction is up. LOL! If they were simply aligning to the magnetic currents, then compass needles would be pointing UP or DOWN depending on how close one is to these spikes in the field lines, or ley lines? Not sure if those apply to magnetics but they DO produce unique circumstances when one can get to their intersecting points...but since they are only rumoured to exist it is curious that where ever they are allegedly supposed to intersect, regardless of territory, there are US Military or other high security facilities located at these points on the globe, even in the other countries, so WHY would that government be so possessive of something that supposedly does not exist or are of no consequence to anything? Can you add 2 plus 2? Well the logic of ley lines being fabled don't add up! LOL! Yes I migrated off topic some, but it often makes for interesting replies and input/feedback! Namaste'! P.S. **Knowledgeable Authority--Google Search results lol...but the more reliable sources like Ask....Dhow...instructables...etc..., however a few of those normally considered reputable, were also misdirecting and adding to the confusion, but compass needle confusion and mislabelling was the final determination, since two of them referenced a compass manufacturer as their source....If you suspend a small or rather thin but long magnet (Cut about 3-4 inches of a metal coat hanger and drag a heavy duty U or horseshoe magnet from one end to the other without pausing (Or you will insert an extra pole in the middle) starting from the S Side and leave it hanging for a while, it will turn to point North-South, and you will have created a new permanent magnet) on a thin thread, away from any other magnetic fields OR metals, it will auto-orientate to magnetic north on its own, and then it will repel that N marked needle on the compass, that's is the checkable proof that N on compasses are actually magnetised to be S!!)

[@sliderulelover]

TheSmokingGun57 All magnets attract opposite poles. The compass is a magnet. It's North pole will attract another magnet's South pole. The earth is also a magnet, a very large one. A compass's North pole (usually marked in the color RED) is attracted to geographic North of the earth. Therefore, since opposite poles attract, the compass North pole is attracted to the earth's South pole, which is located in geographic North. This is what makes it confusing. But if you realize that attraction occurs when opposite poles are involved, then a compass needle's North pole will be attracted to a South pole, in this case the earth's South pole, which unfortunately, is geographic North. It's confusing, but just remember that opposite poles attract each other, so if the needle's North points in a direction, it is actually being attracted by a South pole, in this case, the Earth's South pole which is wrongly labelled as magnetic North. It should be labelled magnetic South to be precise.

[@M4rkpj]

I am a bit confused, I remember from science class that opposites attract and like poles repel, so is the North pointing red indicator on the compass magnetized as a South pole or is the North pole of Earth really the South pole?

[@HyperNova137]

+Mark Paul Jordan They'll tell you that the earth's north pole is actually the magnetic south pole, but these guys claim that is wrong; The end of your compass needle that is pointing to the geographic north pole is actually the south pole of the needle. I don't really know who to believe, but I own one of these biomagnets and the one thing I can say is that you do feel a difference in the effects of each pole. www.magnetage.com/FAQ.html#What_are_the_the_two_different_effects_of_the_North_and_South_poles,_first_discovered_by_Davis_and_Rawls

[@juliusveneziani9455]

+Mark Paul Jordan the geographic north pole is a magnetic south pole

[@HyperNova137]

***** Actually that's wrong (contrary to what orthodox science claims)… Look up the biomagnet research of Rawls & Davis, they state that it's the SOUTH POLE of a compass that points to magnetic north, and claim that the spin of the magnetic fields confirms that the magnetic north pole of the earth is near the geographic north pole.

[@brainiac75]

+Remixomitosis Well, that's actually a quite useless debate of semantics. Nature doesn't know of north and south. That's just a label that we humans have given the poles.

[@HyperNova137]

+Brainiac75 Yes and no. The names themselves are merely for the sake of convention, but my emphasis is necessary for the sake of consistency: The directions of magnetic spin are demonstrably different, so its absolutely wrong to state that the "north pole" of a compass points north. It shouls either be referred to as a south pole or a north-seeking pole. You could just as easily do away with semantic and say that nature doesnt have a north ans south, or any other cardinal direction... but your statement would be the pointless one, because these relative terms have an extremely practical use and we need them.

[@jetlorider]

So it's opposites attracts?...when our north poles(mark red) on our compass points N....that's really South pole of planet Earth....because opposites attracts! so the North pole is really the South pole and the South pole is really the North pole?

[@professorhank2593]

Close, just backwards though. The red end that points to the Earth's north pole is actually the south pole of the magnet. .

[@jetlorider]

oh ok...than why are schools teaching kids that the red part is north side of the magnet?? or is that just a big misconception?

[@professorhank2593]

Probably a misconception on most people's part..and it's probably easier to remember which way is North that way Heck almost everything you learn in on level of school you find out was not quite right, or flat out wrong in the on the next level.

[@jetlorider]

yeah totally....thanks for the insight.

[@quarkleptonsoup]

Henry Sutton At 4:10 of the video he shows that the North pole of his magnet is pointing to the North pole of the earth and he then marks his magnet with a pen showing that his magnet's North pole is the one pointing geographically North.

[@brilyo2962]

the net magnetic lines of force are concentrated on the metal plate at any given point on the surface of the sphere magnet so that it stayed on that one assumed N pole. but, the compass tells us a different story. just my observation.

[@brainiac75]

My sphere is an 1 inch N45. I live in Europe (Denmark) and don't know much about the American market but magnet4less ( .) com has an 1.5 inch N42 sphere for $37.

[@adityareddipalli5433]

Is there availability of small spheres and big spheres compared to 1 inch size?

[@markovelikonja3186]

According to what are you define north and south? If north of earth magnet on north side, then your red part of compas needle is south pole of magnet. In this video is just oposite???

[@wolfgangvonwolfenstien1968]

I was thinking the same thing. 😆

[@strongclassicsonic8468]

No

[@RUS38]

How do you know that the south needle of a compass is pointing to the north pole of a magnet. In theory north pole arrow of a compass is pointing to the geographic north pole of the earth which is actually a magnetic south pole. That means the north pointing needle of a compass would point to the south pole of a magnet? But in all honesty it’s all very confusing because some sources say one thing while others say totally opposite and they all consider themselves as experts. So who do you believe?🤷‍♂️

[@romajikaiser8450]

I have lodestone sphere magnets after using them for quite some time now I have seen were the poles are but couldn't figure out which pole was which

[@threepe0]

I’m pretty sure you marked all of these backwards. The red needle points north, so it is the south polarity of the compass

[@TechnologistLive]

Ok, so explain this Sherlock: which polarity is the north pole of earth if the north indicator of your compass points away from the north pole of the magnet? Meaning the north part of your compass indicates south pole of the magnet. But the north indicator of your compass points to the north pole pole of earth. Waiting ....

[@warmwoolsoxgood4559]

[@ve2zzz]

The Earth's magnetic North pole (in Northern Canada) is, in reality a SOUTH pole. This has been a mistake that has been made centuries ago when men identified magnetic poles on compasses. That explains why a compass's north pole will point towards the Earth's "North" magnetic pole.

[@LJnandSrada]

@brainiac75 Thanks for answering. If I view the earth as a giant magnet, knowing that the northpole of a magnet is attracted to the southpole of another magnet, what you say makes perfect sense to me Thanks, again.

[@2wordU]

Thanks!

[@rival_rebel16yearsago61]

whats the difference between neo and ferrite?

[@brainiac75]

Neodymium magnets are a more modern type of magnet and actually the strongest known permanent magnetic material. A neo magnet is at least 10 times stronger than a ferrite magnet of the same size. The neodymium is however an expensive element so neos also cost a lot more...

[@Zarabozo]

Also, Neodymium magnets are like ceramic in the inside and can break very easily, while ferrite magnets are usually much more resistant to impact.
