Brainiac75 pleas help i am buying 10 pieces of neodymium magnets and and i am being asked about the dimensions so what is the best i am a 1st time user?

[@brainiac75]

+ Omar Taman Hi, you're asking for something I give you guidelines for in this video you have commented on? To sum it up: go for a cylinder magnet that isn't very thin and don't go over 20 mm in diameter for your first magnet.

[@omartaman2419]

Brainiac75 12mm diameter and 3mm thickness nickel coating is good because i trying to get 10 pieces and the asked me about its dimensions so?

[@brainiac75]

+Omar Taman 3 mm is thin for a 12 mm diameter magnet. Expect to break a lot of them if you aren't used to handle neodymium magnets :)

[@isidoreaerys8745]

Very wise advice even after all these years I still get bit from time to time. Many blood blisters in my past. So when a friend casually passed a disc magnet the size of my palm and 2 inches thick to me he was amused by the seriousness and respect with which I handled it.

[@jaythatguyyouknow5135]

I bought some neodymium magnets that are about 1cm wide and .5cm thick and even when these come together it's hard enough to hurt quite a bit when it pinches my skin. It's also nearly impossible to separate them by brute force, without sliding them past one another. Not to mention how many uncoated magnets I've shattered into dozens of tiny, razor sharp pieces by accidentally letting them snap together. It takes a LOT of vigilance to handle even small magnets like that properly. I couldn't imagine a "monster" magnet.

[@jrf0828]

[@ThaitopYT]

My first try is a 1cm disc I bought from a hardware store and I love it. It's so versatile because of the small size, I can use on everything and carrying it to everywhere easily.

[@tomjeffersonwasright2288]

I bought a variety of neodymium magnets, the largest having a 405 pull. Following your advice, I began experimenting with the very smallest, a 39 pound pull, 1 inch cup magnet. I have experience with very large ceramic magnets, so I had great confidence. I now have a small blood blister on one finger, and a greater respect for magnets. Had I ignored your good advice, I could well have had a crushed finger with the largest magnet. Thanks for your fine advice.

I then realised I would be making a mistake and set my sights on the Z-13 set as you've shown here. Alas, the 2 companies I've seen you show in your videos deliver outside europe so I'm now off to see if anyone local (Australia) has them. They probably will, at double to triple the price alas. Great videos, informative and interesting, keep em up.

Thanks so much for your reply. I envision the storage of magnets, much like the storage of isotopes, where they store them in "bird cages" (If you Google, you will see what I mean) where the magnets are stored in a binary fashion, but not in close proximity. Perhaps there is more structural safety in such a binary approach? I wonder at what point do the materials break, and what if we just had just essentially a powder instead? Certainly, a mechanical system could be devised to variably bring many individual magnets closer together, and then seperate them. A simple PVC frame could be used to do that, provided that only smaller magnets were used. How far can you cause deflection of a compass with your large is something I wonder?

[@QuestionXV]

It just so happens that there are a few warehouses of neodymium magnet stores here in Texas where I am, in fact in the same town that I am in. I can literally go over to the place and buy magnets straight from the store. It is the Applied Magnets store. You may have heard of it. There is another one that I do not immediately remember. Applied magnets at one point sold 1/2 inch grade N54 magnets.

[@brainiac75]

+QuestionXV Lucky you :) And yes, I did see the N54 magnets they advertised with. But they quickly stopped selling them - were they underspec or just a one-time offer? I don't know.

[@QuestionXV]

Here I am over a year later, I'm still amazed that I have one of the biggest neodymium warehouses in the world less than 15 miles from my house, I live in Plano and the warehouse is at 1111 Summit Ave #11, Plano, TX 75074, and there is another warehouse, the one for CMS Magnetics, 1839 Wall St, Garland, TX 75041. That should give some people here excuse to move to Texas, by the way, congratulations on almost 200,000 subscribers.

[@brainiac75]

Thank you :) Yes, and I still have to import the magnets from another country if I want a decent size...

Greetings; Any suggestions of what a guy might do with ~20,000 1/2 x 1 n-52 cillinder magnets? Right now they are set up as what'd be best described as a MEG (Motionless Electromagnet Generator) It is about 80% - 90% done. The builder passed on before he could finish his retirement dream. I had planned to finish it, but no longer have the time or the space.

[@karenmmcthree]

Wow. How heavy are they?

[@Nebucatnetzer]

Since ca. a half a year I have a magnet in my finger. It's not very useful except for picking or holding up small screws. However you can feel electro magnetic fields with it which I find really interesting because sometimes you feel it in places you don't expect and in addition it's something a normal human doesn't feel.

[@georgeboulware6073]

[@teletesselator]

If you don't mind a 3 or 4 week shipping time then EBay has a boatload of sellers with excellent prices. Most of them are from China and the finish of the magnets are usually not superb but you can get an N52 40x40x20mm square type or a 40x20mm round type for about $15 and shipping is free. The photos are not faked so at least you can see the finish quality and decide for yourself. I've purchased them from Chinese sellers on EBay and am quite satisfied! Sometimes the dimensions are a bit off. Like maybe you will order a 40x40x20mm magnet and when you get it it's actually 41x37x19 - but hey, that pretty close. And also so far my gauss meter says they are within one rating of what was specified. So if it says N50 on the seller's description then it could be N48 or it could be N52. But in all honesty there is almost no difference between N44 and N52 for example. You can't tell and even the gauss meter has trouble, lifting power is the difference between something like 190kg and 200kg.

[@gristlevonraben]

I'm allergic to nickel. So I'm glad you went into the detail of what they are coated with, thank you.

[@gooscarguitar]

Gristle Von Raben You can also find some that are zinc-plated. They're very resistant to corrosion too, without being as expensive as gold-plated ones.

[@brainiac75]

Gristle Von Raben You're welcome :)FlipUltraHD's advice about the zinc-plated magnets is a good advice. The 4-layer coatings like Ni-Cu-Ni-Epoxy or Ni-Cu-Ni-Au have so thin layers that even tiny scratches will expose the nickel underneath.

[@KingofHearts67]

In my opinion, a long cylinder would be best for a beginner. They are easy to handle because they have a lot of room to hold on to, and can be most easily controlled when letting it contact another magnet or metal surface. I like cubes and blocks for how they look but a long cylinder is most easy to casually play with. I carry a .5x2 inch cylinder magnet with me and it handles pretty nicely. Though do be careful what you set on your lap when carrying a magnet around, I almost ruined my laptop fan once.

[@brainiac75]

+KingofHearts67 Cylinder magnets are the easiest to handle, no doubt about it. I just have trouble with recommending them since you pay for a lot of length of magnet that is not really adding much power. A 10x40 mm cylinder magnet is 4 times more expensive than a 10x10 mm disc magnet. But it is far from 4 times as powerful, only around 20% more pull force... So measured in power a cylinder magnet is not good value for money. It's still a nice magnet though :)

[@sonixthatsme]

Hi Brian. I have a quick question. Is it safe to handle neodymium magnets if you have a steel splinter in your hand ( approximately 3 x 1mm)? Keep up the good work.

[@brainiac75]

[@w8lvradio]

I have some small neodymium magnets here. As you mention, safety and failure of large magnets is an issue. As is their transport and storage. My question: Could one use many small magnets in an additive fashion to meet the same requirements? Do they sum, or do they add in some other fashion?Do you have any recommendauons as to test equipment to measure the field, that is reasonable in price and approximate measurements of the field srrength?

[@brainiac75]

You can use several small magnets to get the same pull force as a single large magnet. The total volume of magnets counts no matter if it is made of a bunch of small magnets or a single large one. Technically a 2x1" disc magnet is a tiny bit stronger than two 2x0.5" discs stacked on top of each other. Due to the two layers of coating going through the middle of the two stacked magnets. In practice you won't notice the difference in strength though. I have no experience with gaussmeters but would really like one myself. I havent bought one yet, since the inexpensive gaussmeters have a reputation of making very unreliable measurements... But for hobby use you may get away with a cheap one from a Chinese eBayer :)

[@nathnullobject]

Hi, could you do a video on repulsion of magnets? In the hifi industry there are turntable designs which use very heavy 10kg+ platters which are then supported from below by magnets to reduce the load on the bearing. I am interested in designing a DIY turntable which does this. The heavier platter reduces vibration to the needle but the problem with the design is the needle is very sensitive to magnetic fields. I would like some advice on how far away a magnet would need to be from the needle to not affect it. Thanks for the videos.

[@brainiac75]

Hm, I have no idea of how sensitive the needle assembly is to a magnetic field. But I do know that hifi-ears can be very picky, so ANY influence on the needle can be a bad thing. Another serious issue is to get the magnetic, repelling fields perfectly uniform so the turntable runs perfectly smoothly without any flutter in the sound. If you are a hifi-freak and picky about the sound I think you will introduce more problems to the sound by DIYing a magnetically floated turntable than the positive effects of a heavier turntable will give you. But I could be totally wrong - I'm inexperienced on this subject.

[@frankiethefrank]

This was fascinating! Please tell me something - if I wanted to create an electric generator, is a neodymium magnet a good idea? I believe I have to drill through the magnet in the centre in order to put the crankshaft into it so that it spins - can this be done with a neodymium? Or would it shatter? Perhaps spinning the copper wire itself is a better solution ? I could use a weaker, 'normal' magnet but I'd like to try to get a decent amount of power out of the generator, I'm assuming a stronger magnet would enable me to do that. Advice gratefully received!!!

[@brainiac75]

+frankiethefrank Electric generators are not my speciality, but a neodymium magnet would definitely make the generator more efficient than a common ferrite magnet. You can't really drill a hole in a neo-magnet. It would ruin the protective coating, the dust/chips would be pyrophoric and the generated heat from the friction could demagnetize the magnet... You should buy a diametrically magnetized neodymium magnet that already has a hole through it. Here are some examples: magnet4less.com/index.php?cPath=1_133

how much do you think a N35 50mm×10mm disc magnet will lift?? 17kilos on rated box but maybe wrong

[@onpsxmember]

Hello there Brainiac, What kind of magnets would you recommend to make a strong durable magnet-rail for tools, maybe one section for heavy tools? I want to protect them with a piece of PP or PA so they won't lose pull from possible hits. At which strength is it possible to damage electronics in certain range? Would be great to pick your brain. Or maybe you could do a video about it.

[@brainiac75]

Hi, I have no experiences in making magnet rails myself. A nail still works best for hanging tools - especially heavy tools since magnets don't like shear forces ;) You may find some inspiration and more details here: www.kjmagnetics.com/blog.asp?p=magnetic-knife-holder www.supermagnete.dk/Magnet-applications/Hanging-Tools-1 Distance to electronics depends so much on the kind of electronics and size of magnet, so no way to answer it shortly. Generally, most electronics are very sturdy to permanent magnet fields. I test some random electronics near my largest magnet in this video: kzbin.info/www/bejne/laqopmWIZsyMidU

[@nikhil7229]

Does the weight of the magnets affect the pull force?

[@brainiac75]

Yes, in the way that a bigger, heavier magnet will usually have higher pull force than a smaller, lighter magnet. But it is also highly dependent on the shape of the magnet: A flat disc magnet will have higher pull force on a large metal object than a very long rod magnet with the same volume/weight. Simply because of a larger pole surface being in contact with the metal object.

[@nikhil7229]

+Brainiac75 you said that the gold coating was not an enhancer of magnet strength but it is an excellent conductor. two questions. (and please don't electrocute yourself experimenting) 1. can you turn a regular magnet into an electromagnet through some simple process? 2. if you apply electricity to a magnet coated in gold, how much electricity would it take before the coating melted off? 3. is there a coating that can be placed on a magnet, that's as conductive as gold, but has a higher melting point?

They must me Neo's because they are very strong, I might venture to say probably 48's, if they are 52's I am very impressed. Either way they are round and BIT. The Magnets pulled from hard drives are very powerful, surprisingly powerful to say the least and I left the metal attached to them as it seems to control their power a lot and makes them far easier to handle. Even with the attached metal shield they are still fun to play with, at least I know I will not crush my fingers with them where as if they are removed from their shields they will be very dangerous to handle. Thank for sharing this awesome video....

Paul Bialozor Hehe, yes they are surprisingly powerful. They seem so innocent until a large piece of metal comes close to them...Neo magnets from scrapped hard disk drives are a cheap solution. But opening the hard drives and removing the magnets from their brackets is not always easy. And the magnets are quite specialized (my video about them: kzbin.info/www/bejne/m6HCh3alqaZkkLs). But especially the really old hard drives can have some large impressive magnets. Thanks for watching and commenting!

brainiac75 Great to know, I have some very old Hard Drives, like 200 MEGs not GIGS, Megabytes... I look forward to dismantling them...

Could you please link to the Datasheet of Magnetic Care or Warning. Thanks...

[@brainiac75]

Sure, it's already in the description box under the video. Thanks for watching!

[@Storm-tg8rx]

would you recomend a lot of small magnets or one big magnet?

[@brainiac75]

Depends a lot on what you need them for? For my experiments I often need max power. For this, one big magnet beats a lot of small magnets. For playing a lot of small magnets can be very fun, like the typical cube of 216 sphere or cube magnets being sold in many places.

Gotten my set coming in the mail, followed majority of the guidelines you stated, probably somewhat of a slightly larger magnet (.56 in^3) but pretty close.

[@brainiac75]

As long as you're prepared and don't start with slamming the magnets on a large piece of iron with your fingers between, you'll be fine :) Thanks for watching and good luck with the magnet.

[@ChefBuckeye]

Brainiac75 Well they arrived today, probably my happiness took away part of my preparation as putting them on a table and the magnets swiping around the area ends up two chips from two of them coming off. I decided to put the two that shattered away to keep them away from moisture so they don't corrode as quickly. Well thanks for the good luck, although maybe a shatter there's always plenty of time to get better handling the magnets. :)
