Is it just me or are magnets really attractive
GET OUT!!!!!!!!!!!!!!!
Loooool
Nice one
The puns are killing me
Polarity counts for something, I thinks.
It's because melting them or heating them to a point destroys the molecular alignment that causes magnetism to occur.
Side note: Igneous rocks actually cool down with their molecules aligned with the earth's magnetic field at that time, allowing us to very accurately track Earth's magnetic fluctuations across millions of years. A magnetic snapshot of the past.
This is how we know about the reversal of the poles. :-)
Why don't the magnets realign with earth's current magnetic field?
Piper Landry My mind has been blown. Wow.
You should read about the "Curie-Temperature" of a magnet. Neodymium magnets have a curie-temp of about 350 degree C. That means at this temperature the material loses it's magnetism completely and permanently.
Semi permanently
You still can re-magnetize them
:O how?
The issue is that each grain is oriented in a different direction, meaning that the net total of all grains cancel out to no direction pull. You need to polarize the material to orient them all in one direction again.
They also get stronger when they are cooled
I was wondering how he doesn’t know that heat removes magnetism
I got thought that in 3rd grade
So what happens if you put a magnets in liquid nitrogen and super cool them do they get stronger
Bro he's dead
It gets stronger
No
Look up a mobius strip
Nikolai Orr How does that have anything to do with magnets??
well it is possible to reactivate the magnets by reheating the magnets to round about 2/3 of the melting temperature and while let them slowy cooling down, expose them to a strong electromagnetic field. this will give the randomly ordered magnetic molecules the chance to re-aligne in to the into the proper magnetic order and maintaining that position.
This meaning we can defeat Magneto by sending Human Torch.
Saiful Anwar Hamdan you have no idea what Magneto's power really does? Do you?
He means the supervillain, not the generator...
This is my favourite comment I can die happy now
OneEye Gentleman this comment made my day
OneEye Gentleman like 1500 f°
Edite: the metal drom the comics has magic in it so it near impossable to melt it down
Well, I just found out a way to defeat Magneto. He teamed up with Pyro for a reason.
Glad I'm not the only one that thought defeating about Magneto lol
Irventor also Dr. Doom
Irventor lol
LOL
You have to keep a strong magnetic field next to the magnet while it cools from red hot or it'll become randomized and be very weak magnetically or not at all. That's how they make them. They heat them to glowing and then put them next to a powerful electro magnet while they cool to align the fields.
I heard magnets actually get stronger when you freeze them. I was wondering if in your next video you could do the opposite with the magnets. Maybe dip them in liquid nitrogen.
Zeldas Champion electro magnets do but don't think these do
i was going to ask the same thing!
You can't freeze a magnet, because it is already in a solid state.
John Bond by freeze I would presume he meant cool
John Bond he means cooling it you nub
So Human Torch would win against Magneto?
Hmmm there a chance........unless magneto slam him with iron stick at high speed
There is difference between magnets and electromagnets. Magneto's power based on electric magnetism.
I'm going to move this coin with my mind on the count of 3. 1...2... *throws coin* ...3...
Huh? You mean what Magneto manipulates is actually electric current and the magnetism is only secondary effect?
Just heat the metals, whatever magnet it is lose effect then
Great video! I was looking for melting magnetite videos and came across this one. Answered a lot of questions. Very well done!
4th grade lesson taught to me in 1964: Heat demagnetizes anything, including magnets.
Tell that to SiC
Yup, heating and beating, learned it in secondary school sixties.
what if you froze gummy worms in liquid nitrogen, crushed them into powder, and put the powder in a cotton candy machine. will it melt, or become cotton candy
CableGG Slimes 🤔 💭
Sounds delicious. U sir, just invented a candy idea.
This is the real question
I must see this happen
So basically to defeat Magneto you just have to raise the heat
He controls metal not magnets no
Yeah, but if the metal is hot, he can't control it.
He controls magnetic and electromagnetic fields not metal.
Rory, so what's your point? He controls magnetic fields and through them magnetic materials. The point here is that his "power" is useless when any magnetic materials (materials reacting to or being influenced by magnetic fields) are above a certain temperature because they lose all of their magnetic properties and his magnetic fields don't affect them at all.
Edin Fifić he has the power electromagnetism meaning he can control most if not all electrical currents meaning his power to control electric wouldn’t be affected by heat. Plus it wasn’t your comment that a replied to.
why does he wear thin rubber gloves when handling hot materials?
So he doesn't get his dish wash soft hands dirty.
The gloves may look thin and crappy. But those gloves are actually quite awesome. I've even seen chefs use them to prevent cuts.
No idea.
@@seofra8252 They're just gloves... You can get those exact gloves at harbor freight.
@@seofra8252 we chefs DO NOT use little black gloves to prevent cuts..we do have gloves for this purpose, but not the ones you see here. They're much thicker and not made of rubber.
2:24 ‘that din’t last long’
That what she said
I don’t get it
Two suggestions:
Find a way to mix your glow-in-the-dark liquids with a bubble solution, or see if the dish soap enhancement to increase it's glow also works to blow bubbles. Glowing bubbles are always fun.
Also, we've seen that extreme heat ruins a magnet -- what about extreme cold? Do magnets work after being submerged in liquid nitrogen? What about steel that's been submerged in liquid nitrogen -- does it still attract magnets just as well as it would normally?
Growing up I use to make my mom nervous playing with a wood burner in the house... and at Grants house he has a homemade arc blaster in the basement haha
He made it himself from pieces of an old microwave
@@the_shadow_hog and fire brick
So this is why when the Sun throws a solar flare the Earths magnetic field also gets weakened. Same mechanics?
Dave Rios yes, because solar flare means radiation and radyation means heat means weakened magnetic field.
@@MuhammedhilmigulluBlogspot That does not make sense considering that earth is heated up from inside and it does not affect it
You know those gloves... can melt and stick to your skin?
Or even melt into skin

Do you follow SSUNDEE?
Interesting. I suggest flaming gas filled tennis balls from a potato cannon.
WHO ARE YOU? AND WHY ARE YOU ON EVERY VIDEO COMMENT SECTION I SEE?
Lots of misinformation about Nd magnets here. Neodymium magnets are not "mostly neodymium"; they're mostly iron. The approximate formula is Nd2Fe14B, so Nd only makes up ~12% of the alloy. The fact that it is an alloy would only serve to decrease the melting point, not increase it. Thus they should melt a bit below iron melting temperature. It's possible the cylinder magnet had a hard time melting because of low contact area between the curved surface and the electrodes.
Also, I understand you do things solely for entertainment, but you really should have at least mentioned the concept of the Curie temperature. It clearly explains what happened to the magnets. A minimal amount of research would really help improve your videos.
Alloys do not always decrease melting temperature compared to pure substances.
For an example which is simpler than thinking of metals: Mixing alcohol with water increases the boiling temp compared to alcohol but decreases compared to water. This is something you can experiment.
Another example, but more complicated, is mixing indium and gallium which are both solid at room temperature, but the simple rubbing together creates a mixture that is liquid.
So your statement was wrong. Proper statement:
Due to the fact that neodymium (high melting temp) is being mixed with iron (lower melting temp) and assuming that the mixture is ideal (or aprox ideal) in its behavior, then we can say that the melting temperature will be between the two.
The melting point can increase, compared to the pure substances, if the mixture diverges from ideal behavior in a way that makes it energetically favorable to be a solid.
For example, if the mixture leads to massively increased interactions between their potential wells, for example very close bonding, then we will get a mixture that has a higher melting point then either of the pure substances.
Also, these guys make videos for a certain crowd of people that don't really care about the science behind it, and that's fine. Not everyone has to know everything all the time.
He was using temperatures well in excess of the melting points of the materials. Nd Curie temp is about 350deg. Nd melting point is about 1100deg. The composite magnets are not melted when created for a reason. Nd melting point is several hundred degrees below iron btw. Iron is around 1800 deg. So the ovens he used obviously worked, but I would love to see an inductor as they use in vacuum deposition.
Peoplezk1 A solution of alcohol and water will boil at the temperature of alcohol until the alcohol is gone. Boiling and melting are governed by different laws of physics. What Mrhomescientist said is true, an alloy will always have a lower melting point. Stainless steel is a great example as it has a melting temp lower than both the iron and chromium it contains.
mrhomescientist please be my chemistry and biology teacher 😂😂😂
Not true... It will boil until you get a solution that boils at a slightly lower temperature than alcohol. Search for azeotropic mixtures. By distillation you can only separate water from alcohol (specifically ethanol) to approx 95.6%. The azeotropic mixture of water an ethanol boils at about 78.2degC while pure ethanol boils at 78.5degC. The opposite is true and some azeotropic mixtures have higher boiling points than the components in the mixture... Or something like that ;) I have no experience on metallurgy though...
I work in an iron ore mine where its reservation of (FE) it’s magnetized by nature . You could stick a coin in the dirt , and the metal sticks to it . Amazing video 👍👍👍
Magnets and metals attracted to them lose such properties beyond the CURIE TEMPERATURE being exceeded. I think this is around 250 deg C.
Also we will all miss this guy.
Is wearing the plastic gloves the best idea??
yes
When working with hot stuff no
yez
Better than nothing
gofofgamers - How about when the latex melts to your skin?
How about using an electromagnet (coil) to magnetise them again
Le Olaf I was thinking the same thing. That's how most magnets are made, they use an electromagnet to align the field to a uniform direction, so I don't see why that wouldn't work here lol
Le Olaf that would be awesome to See
Try this with the degaussed neodymium magnets!
Build a electromagnet using the transformers from the microwaves and 10 gauge wire. Wrap it around the arc furnace, now you have a magnet making machine.
ItsAKaime so you could make your own shaped magnets right?
Learned how ceramic acts in a fire as a kid when me and a friend threw away some old ceramic dishes in the burn pit. We took shelter in his truck until they stopped popping.
It's funny.... Heating the magnets causes a loss of magnetism, yet super heating iron, such as at the earths core, creates magnetism.
The earth's magnetism is electromagnetic and electromagnets don't have a curie point so therefore the temperature doesn't have anything to do with it
@@a.r.ripley2582 I did not know that, thank you.
I guess you can say it's *IRONic*
It's not only Iron in the Earth's core but other metals; specifically Nickle; at different temps and direction of rotation, that induce the electromagnetic field.
@DjJtown Thats true, but I saw an oppertunity to make a pun and just took that oppertunity jfbehgvbrhfjhffjhf.
does magnet gets stronger as we decrease the temperature?
(use liquid nitrogen)
Shady i dont think thats how it works
Answer: no, the magnetic field is trapped in the material and heating it up releases that material. Cooling it down only prevents it from escaping, but you can't create a more powerfull one.
Freezing the magnet will create quantum trapping in the magneting feild
Cooling the magnet makes the particles move more sliwly allowing for better alignment and results in a stronger magnetic feild. All you kids saying no should do your research before commenting. Fra32 cough cough
tyler hickling exactly. These kids understand nothing
Place a coil of wire around the furnace. Allow some electricity to flow through the wire, creating a magnetic field while the steel is melting & cooling... Then what happens?
That's called an "Induction Furnace".
Glenn Gutshall
Not a bad idea, but it won't work.
Isn't that a solenoid?
The current must be DC, not AC, and it has to be reasonably strong. Cooling the alloy from above the Curie temperature to below the Curie temperature with presence of an external magnetic field (from the coil) would magnetize the alloy.
An induction furnace uses AC to generate a rapidly fluctuating field that cause the metal inside to heat up. What Glenn is talking about uses DC.
I really needed to watch someone melt magnets. My life is complete.
Suggestion! ⚠
Put the magnets in a block of ice with a hole or hollow for them to sit in, see if any magnets have enough attraction to break the ice or force a way through.
Show how to remagnetize the magnets you've demagnetized.
See if you can melt down a magnet and cast it with another metal, find out what happens.
What happen if you melt kinetic sand?
Is it make kinetic glass? lol
Anthony The hmmmmm ?😂
Anthony The interesting
It's a very nice experiment
Lol
Do you not know what kinetic sand is?
Magnets always lose their magnicity when heated to a certain temperature
The curie point, a temperature at which a material loses all permanent magnetic ability.
SynthFrost he probably knew that, but well a video is a video, and it seems a lot of viewers don’t know that
Yeah, I was like "duh, Curie point" ... I'm curious if the magnet that demagnetised after sitting on the cooling magnet did so because there was enough heat left. As for the ceramic ferrite magnet, the result is kind of obvious when you think about the name: it's a ceramic containing a lot of metal particles.
Magnicity?😂😂
I’ve been looking for this video for years
"Oh Jeeze" LOL that was pretty funny!
Every year you should invite a random fan to do an experiment with you
Junkrat 82 more like every month
More like every week
It's because if an object is hot the atoms and elementary parts are moving very fast and this causes the elementary magnets to lose their order and their magnetic attraction
thank you
Florian Sattler Ya, me too!!
@@darrenkastl8160 .
Its because when a magnet reaches a certain temperature called a curie point its attraction no longer flows outward, but inward. Essentially it attracts to itself because the heat loosens up the atoms in the magnet and then those attractive atoms attach to eachother. This also causes the center of he magnet to retain a slight magnetism
You guys should try freezing magnets and steel with liquid nitrogen and do similar tests.
agreed
@@leoliu6469 agreed
*Magneto should watch this*
We should burn magneto to make him lose his power
Or Polaris
His enemies should watch this
Can you try making a big electric arc furnace?
The dipoles of the magnets will have high kinetic energy thus increasing the entropy within the system making it less magnetic.
Trivia: He pronounced the word magnet for over 60 times in the whole video
imagine melting monster magnets
john johnson I cant see ur comment lol
Nearly 10 million
I think you might want to try that idea you had at the end to set up a version where the B field isn't disturbed by heating the magnet you're trying to use to set the standard magnetic field.
I'd love to see you accomplish it without an electromagnet.
As soon as you heat a magnet lose the magnetism. You need to put the cooled magnet into a high magnetic field to codify the new magnetic field into the magnet. You can do that when the magnet is cold, or when the magnet is cooling down.
Hey i hav a question.... We know that earth's magnetic field is due to flow of ions in the core. But if heating ruins magnetic effects then what's the cause of earth's magnetic field??
Completely spitballing but I would assume the rotation of the inner and the (relatively) stationary outer act (somewhat) like a generator and a current is induced in all the metal within the crust which generates the magnetic field normal to the axis of rotation of the core. I'm gonna check the wiki to see if I was even close.
My guess was pretty close.
Yeah i too searched it..this thing works due to the reverse dynamo thing...you were pretty close dude🤘
haha i was just thinking about this when i watched it... i believe however that it may be due to the solid iron in the crust... the liquid metal moving around inside of the solid iron makes a magnetic field much like how a electric motor creates a electric field, just having the mass if iron rotating inside of the iron shell.... but i serously was wondering about this for like 20 minutes after watching this vid dude
Gravity works different than magnetic field.
What happens when you put glow stick juice in liquid nitrogen?
LilFrap it would freeze quickly, stopping the rxn?
Thanks for this video....I'm saving it to my data for educational purpose
Magnetism means the atom mass is in alignment. Alignment is what creates the magnetic pull. When u heat it up, it expands and excites the particles causing movement. This movement misaligns the atoms which removes the magnetic properties. I am an aerospace engineer so this isn't my field of expertise but i hope this info helps. I believe it is the electrons that align, hence electromagnetism.
Try cold welding different metals in your vacuum chamber
Try to molt steel(or any metal that can be attracted by magnets) while it levitates via a powerful electro magnet.
When it comes to electromagnets it does not make much of a difference if metal heated up or not.
Donatien Alphonse François de Sade but still it will be cool
I always wondered what those pieces of metal that stuck to other pieces of metal were called, glad I saw this video.
This reminds me of Charlie day from it’s always sunny saying his favorite hobby is “magnets”
7:16 idk that look like a frog 😂🐸🐸
I Love ur videooo 💕🙌
Try melting cured silicone and see if you can recast it.
Ceramic magnet shattered due to uneven heating, like you would get with glass. Heat it slowly.
I've seen an experiment when a magnet is heated on an electric stove and it loses the magnetic attraction even when it has cooled. After hitting it with a hammer the magnetivity returns
Can you try MAKE a magnet? (A permanent magnet, not the temporary/electro magnets)
Milo Legends from what i know u cant
Um, what, you think all commercially available permanent magnets are like, dug out from mines or something? Of course you can manufacture a magnet.
That's what letting hot ferromagnetic materials cool in a strong electromagnetic field (as suggested at the end of the video) would do.
evan otha you can
Man, its izi. The magnetic field is created by the arrangement of the particles, if you get a hot metal and force a huge magnetic field (neodymium/electromagnet) while its stills red, and let it get colder, once cold the particles would still be organized in that way, creating a magnetic field
Can u guys make a lighter that can switch between colors of the fire??
Just Because
its not that simple
GrittZ that's why I want them to try
Great video! But doesn't everyone know that magnetic domains in the magnet get all jumbled up when it's heated? I mean when we learned that in school, they trusted 3rd graders to use bunsen burners to demagnetize a magnet we made from a magnet...
Okay, well here's an idea: take a strip of thin magnetized metal and twist it into a mobius strip, then cut it down the middle and see if it will make a wint-o-green lifesaver glow in the dark while in a centrifuge!
Those poor tongs
I love your shirt
3:00 actually they're still mostly made of iron.

“So we’re going to melt down this then this and then both.”
(5 seconds later)
“So we’re going to heat up this then this then both”
(5 seconds again)
“Alright let’s melt this,”
Scientifically magnets should lose their attractive forces (Magnetism) after it's heated, so it won't attract anymore
kr4zyy yeah.. didnt everyone hear this? I thought it was common knowledge, to get rid of a magnetism in a metal heat it
And to add it electrify it (if im not mistaken)
OverKnight 52 you can also run a magnet against metal to magnetise it, like those small keyrings with a magnet so you can magnetise a screwdriver
kr4zyy Scientifically, the earth’s molten metal core should not be capable of producing or maintaining magnetism; but thankfully MAGICAL SCIENTIFIC FAIRY FART DUST permits it to retain its magnetism beyond the Curie Point. . . And if you believe that I have a bridge for sale in Brooklyn. . . So much for lience, I mean science.
Try spinning a huge amount of molten metal through a magnetic field and see what happens....science!
IamNemoN01 Probably not a molten core indeed. I think more like duality becomes trinity.
a cool experiment you guys should try is making lichtenberg figures in glass or plexiglass I have no idea how you would go about making that but if u could I wonder what amounts of electricity can you get from the smaller sparks that can go on for 20 minutes or more
I had no idea what this even was but I looked it up and this is so amazing I wish I could try it at home but it would be cool to see the different experiments they could do with this
That's not the same as if it's on wood, trust me. Both glass and plexiglass much less capable of absorbing liquids, so you won't be able to carve figures, cuz, liquid conductor would just vaporize before it can heat up properly.
no look it up lol its like trapped lightning its way cooler trust me
Take two neodimium magnets on either end of a glowing yellow piece of steel. The two neodimium magnets need to have both attractive sides facing each other on either side of the hot steel. Theory is as the metal cools it will become magnetic itself because the neo magnets pull the positive and negative polls in the steel and holds them aligned as it cools.
6:35 motorcycling is one of the three awsome actions you do in that pose 🤘
Not even a little bit weird.

Sand cast with molten salt please
So what I get from this is the Earth's core cannot create a magnetic field?
I have same question like you 🤔
Yes. There is no magneticness in the center of the Earth
When you heat a magnet, give it shocks (like hammering it) or set two magnets together on their opposite sides, it’ll lose it’s magnetism
"Melting Magnets is Weird"
No, it's not...

The strongest acid has a ph value of -3 and the reaction with a base is quite exotherm, so fun to watch if you mix alot of it together.
Thats right, and thats why i dont want to see a guy like him handling dangerous substances, he should stay by his Magnets and similar basic stuff, i still cant belive he is still alive with this electrodes in his hands trying to melt something down...
It would probably create the world's most toxic salt. Lmao.
Game Predator water
As an apprentice blacksmith I can tell you even before you get into the video that the materials will NOT get attracted to each other while significantly hot. This is because the crystals of the metals become deformed and thus unable to hold a magnetic alignment. We use this to roughly tell temperature and to tell if we have significantly/correctly heat treated a product. Also in relation to the ceramic magnet shattering: you heat-shocked it. It was cold when you put it in but the temperature was too hot for it to stand rising to so fast. The same property can cause even modern blades to shatter/crack.
Neodyminium magnets are ruined above 80 or so Celcius. So if you want to magnetize a cooling magnet either use insulation in between, use a magnet that can withstand higher temperatures such as AlNiCo or use an electromagmet. Electromagnets can be even more powerful than neodyminium.
When I turn steel without coolant then the steel and the HSS-Tools are becoming frick'n magnetic til it's getting warmer.

Magnetism goes away when steel is hot enough, it's actually a teqnique to check the temperature when blacksmithing and knifenaking
I wasn t sure bit I suspected this result. The magnets what ever kind they are, are ionized and when heated those ions are allowed to move so the whole positive and negative sides are canceling them out like the natural metal they are derived from

Here’s the ultimate video for you. Take two of the strongest magnets you can legally buy. Drop one in a vat of liquid nitrogen or something colder like helium or oxygen. Then drop another into a forge bringing it to the highest temperature you can before it melts. Then see if the super charged frozen magnet can attract the red hot magnet. I would recommend not being anywhere near the experiment though.
Augh, you just destroyed a perfectly useful neodymium-iron-boron magnet! Those lose all magnetism it they’re heated up to above 1000C.
Whenever something squirts, you say: "that's exciting" like when the steel sparked(squirted) pr the time when a battery squirted, and you said the same thing.
i wonder what he would say if his pp squirted
Ahh....Only 1 MIL remaining.......your subscriber from 4 Mil or so.....Miss those old DIY days

The ceramic magnet shattered because of thermal shock, not because of any magnetic property it holds. Ceramics will shatter when the temperature of the ceramic is unevenly heated. I would say try slowly heating it, but heating a magnet is a known way of destroying a magnet, so it wouldn't be very interesting.
Some Blacksmiths actually use a magnet to test their temper because the temp where they lose magnetism is the perfect temp for tempering.
magnet magnet second magnet first magnet attracts to the magnet that has been heated so the magnet loses its magnetic power.

who got confused reading that xD
Wow, thanks for playing along guys.
5:39 ooh this magnet got ruined
Giving a hotter temperature , means more kinetic energy to individual atoms , at certain points they start breaking off from their aligned states, leading to a loss in magnetism.
Create an electromagnetic tube that has heat protection in the center that doesn't block magnetic waves, heat the metal to various temperatures, and see how hot you have to get the metal to transfer the magnetism to the metal. It there should be a specific temperature for the poles of the atoms to shift, to make it magnetic.
