[@DANGJOS]

Above the Curie temperature, the magnetic moments in iron are randomized by thermal motion. It is no longer ferromagnet, but a weak magnet called a paramagnet, who's spin only aligns in a magnetic field.

[@bucky13]

Yea, I was face palming so hard. He got a false sense of security from picking up the little pieces of iron. The bigger the chunk of metal, the stronger the pull. If he were to do that with a 20lb steel plate or another strong magnet he would have lost some fingers. It's common sense! You don't restrict 800lb pull magnets with your own flesh.

[@popeyethepirate5473]

I'm a blacksmith and when I saw you where trying to get molten iron to be magnetized I knew nothing would happen.

[@Abrexas90]

I actually felt a bit dumb when I was surprised that nothing happened. I thought it was ubiquitous knowledge that magnetism was lost at high temperatures. But I guess this surprised me because I'm used to thinking of this is the sense of heating up a magnet itself, and not heating up a magnetic material. I'm jealous of your trade though. Something I would love to hobby in at some point.

I was about to comment the same thing. As a scientist, he should have realized that the melting point of iron is above the curie point.

[@faxezu]

You are right, it's going from ferromagnetism to paramagnetism over the curie-temperature. But paramagnets are attracted in a magnetic field ( e.g. your magnet sticks to your fridge )too. So at least something could have happened.

[@fredlllll]

thats what happens if you dont listen in school.

[@CarterColeisInfamous]

as soon as it gets hot it will destroy the domains and not be magnetic any more

[@maxk4324]

i was thinking that, im sure it looses magnetism under extreme heat.

[@azreal289]

Okay man, lets go through some basic metallurgy. I forgive you for trying this. I came just to watch the thermite because I knew after reading the title it wouldn't work. As you are aware, blacksmiths heat up metal so that it becomes soft enough to pound into shapes in a way that doesn't ruin the structural integrity of the crystals. The science here is that when iron heats to a point that it is easily shapeable, it looses its magnetic properties. A common trick for new blacksmiths that don't have a thermometer and don't have enough experience to visually observe when metal is ready to work, is to use a magnet on a stick. When the magnet does not stick to the work piece, you know you are in business. The molten metal is an even higher temperature than what blacksmiths work on. The magnet can not possibly stick.

[@dealwitit6563]

the magnet was working fine, he literally explains why magnetic materials stop working at high tempuratures at 2:53, at that point in the video the magnet still worked fine... I've seen so many comments like this one, like obviously some people either didn't watch the video or didn't pay attention too well lol

[@S41t4r4]

You was the one who didn't watched the video at 2:53 he literally destroyed his magnet and then he explains why. it is also the reason why liquid metal has no magnetism. In regards of the target group of this channel the explanation coud be better formulated.

[@Sander_Datema]

You know you could have used that magnet to turn that molten iron into a magnet when it cooled right? All you have to do is melt the iron, and then put it into a magnetic field as it cools.

unfortunately iron and steel loses its magnetic properties after reaching a certain temperature, in fact using magnets is a common way blacksmith's figure out if a piece of steel has reached a certain temperature.

Metal turns nonmagnetic after it reaches a certain temperature. They use magnets to know when steel has reached the correct annealing temperature.

By the same token, halving your distance from the source quadruples the amount of force or energy you receive (this same law applies to any kind of field that expands outward evenly in three dimensions from a single point, like gravity, or heat, light and sound energy). My point is, with the distance his hand created between the magnet and the metal bits, the force would not have been 800 lb even with a flat sheet of metal... the magnet would have to be actually touching the metal to see its maximum strength.

[@soulreaper6568]

+Ausogiea fare point

[@squidcaps4308]

Was looking the same, a bit careless handling of dangerous objects.. We use them for dent removal on brass instruments and there is no way i trust that my hand is keeping the right distance every single time.. You need to handle them like explosives, really really think every move you make as it is really easy to forget, they are just a lump of metal in your hand. harmless, feels inert and the inverse square law makes it feel safe. Accidents happen on these in a microsecond and never when you are actually working.. They happens when you are not looking, just finished your job and you check the finished work and boom: fingers between a vice and magnet... Right at the beginning there sis a clip where magnet was used unsighted, under a plank without prior inspection of loose metal objects.. yeah, kids, don't do this, do't take your eyes off from it, check with smaller magnets if there are loose bolts, nails etc. before putting your hand in there with the death machine.. Mr backyard scientist needs to seriously learn how to handle large rare earth magnets or he will lose something. They really, really are not a joke and thinking that they will explode is a good trick (they won't but they will shatter quite easy)... It is good that he got nicked at the end as that lesson really was overdue. This guy is brilliant and makes awesome videos, don't want something as stupid as this to stop it. He will will loose a finger or two unless he checks his protocol.

[@martind.5257]

That's what I wondered. He is so awfuly uncareful in every of his videos

[@jakedg4870]

i guess he gotta fall on his nose hard before he gets some common sense

[@devoltar]

No doubt, this guy is poster-child for "Don't try this at home". You *never* put your hand between a rare earth magnet and anything it will attract, esp if you aren't certain of the iron content. Even two small rare earth magnets can snap together and crush finger bones - an 800lb magnet with a big enough piece of metal can crush pretty much any part of your body. He only made it out with so little injury because the items that snapped to his hand didn't have enough metal to generate that level of attractive force (low saturation). Of course I think he realizes the limits he pushes, but I do kind of wish he'd remind people, because some of the folks who watch these videos aren't savvy to the science or the risks. Braniac75 has some great videos for showing just how dangerous big rare earth magnets are.

[@byby488]

because it would have been very difficult to remove all the microscopical iron bits from the magnet. That thing is pretty strong.

[@devoltar]

You use a board for that, not your hand.

Wouldn't the high temperature demagnetise the magnet suddenly?

[@BBSHOCKZ]

are you referring to the Earth's core?

[@jamesleatherwood5125]

Before conclusion. Paused at thermite burning. So. As someone with amateur blacksmithing experience, iron demagnetizes before it even melts. Its actually a target temperature to the point of most blacksmiths having a magnet close by while smithing to check for that very demagnetization. So, theoretically, because the iron is demagnetized (or mabey thats the wrong word... has become non magnetic?...maybe) it should not respond to the magnets field no matter how strong it is.

[@jonathanavelar9897]

I like how you just do some high heat stuff right on the grass.

steel and iron loose their magnetism attraction at about 1800 degrees Fahrenheit

Ok yeah he explained that after I said that^ so yeah

[@HealthyFamilyVarietyChannel]

But yeah, I remember that from junior high science......so, being super smart, he just did the experiment to ???teach us again??? For those of us that slept through class? **His pool on fire vid was much better.

[@kevthomas1179]

" oooh that really hurt" ....wear the damn protective equipment

[@Dunkle0steus]

One of the ways blacksmiths can tell if their metal is hot enough to quench is that steel and iron stop being attracted to magnets at high temperatures. I don't think molten iron reacts much at all to magnetic fields.

[@lemonke8132]

Isn't it common knowledge that really hot/molten metal isn't magnetic? I'm going into my sophomore year of high school and even i knew that haha

[@TheBackyardScientist]

+Definitely Not B8ing I must've missed that lesson but I was thinking spinning molten metal makes a magnetic field so...

[@MisterCoolman29]

+TheBackyardScientist it's because of the elemental magnets inside of ferromagnetic metals, when heated up, the elemental magnets start moving quickly and getting out of order which causes the metal to not be magnetic for the time it's molten

[@PYROHIAN89]

youtube tought me that

[@Mrkevi123]

It's not common knowledge since probably 99% of the population don't understand how magnetic fields work. I'm an in Engineer and I remember bot even learning it in physics but in manufacturing engineering class.

[@peterawesomeness1]

I'm sure he knew that. The point of this video was to prove that point through experimentation.

[@fortunateson6070]

Funny, suddenly that magnet got smaller

hypothesis? or knowledge of metals being heated to a certain temp and thus becoming ferromagnetic?

DoinItRightTheFirstTime Neo magnets can withstand MUCH higher temps then plain Iron alloy ones. I was pretty sure it would die, but not completely sure. :D

[@tux9656]

I wonder what would happen if you got a magnet like this extremely cold using liquid nitrogen.

Meissner effect. But anyway, these guys work best at lower temperatures, eg Low temperature superconductors. eg niobium tin.

[@tio4973]

A magnet would lose its magnet ivory if it got too hot or too cold

[@caiodollis6159]

When iron passes a certain temperature, its ferrite structure becomes austenite, an iron allotropic form that is non magnetic. Magnetism is not inherent to the element, but to the atomic structure. Fun fact: Most of the stainless steel are non magnetic because the ferrite was transformed into austenite and the nickel content stabilizes it at room temperature

[@gorisenke]

+hedgty I don't know, you might not lose your data, but I feel like the pull from the magnet might actually move the components inside and keep the device from working. I've done that to completely destroy hard drives before. Left a magnet (nowhere near this strong, but strong) on it for a weekend and it completely warped the bits inside.

[@DeuxisWasTaken]

A strong enough magnet will indeed destroy electronics, as anything magnetic will get pulled towards it. Also ruins and parts that are magnetic like speakers, microphone, some forms of storage...

@@styxscorpion4541 no he means liquid iron. As in iron in its liquid state, which is the same as molten iron. By putting iron fillings in a liquid (usually oil if you are referring to ferrofluid) you are making a suspension of solid iron in a liquid - not liquid iron.
