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.
bucky13 lol He has NO clue. Any adult with half a brain knows exactly why it's moronic to buffer that powerful of a magnet and magnetic metals. You will crush your hand accidentally if that's a common practice of yours.
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.
Absolutely! Iron lose its magnetic properties when it's molten... His magnet has only influence on iron during cooling process, that's all... And a heated magnet lose its propeties too... It's a useless experiment!
Prediction before watching: The magnet will have no effect on the molten metal as it is waaaaaay above the curie temperature for iron (not to mention the atoms aren't even in a solid lattice). Now lets see how I did.... Edit: Yup, I was right.
@Bennet Olander I was simply making a game out of it for fun and commented so that I might see if others had different pre-watching predictions they'd like to share. I was not trying to boast or sound condescending, but my apologies if it came off that way.
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.

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.
Now backyard arsonist, if you'd just known the concept of Curie Temperature this experiment wouldn't have to be performed in the first place. Iron is only attracted because of something called Ferromagnetic Domains and at high temperature those domains get destroyed and iron turns paramagnetic .
This is an old blacksmithing trick. When metal hits a certain tempature, (usually before molten) it becomes non magnetic. This is why it wasn't affected
+SilentDarkness Attack before he poured anything on it. you see the scene before the magnet is almost as big as his hand. the magnet in the shot after is a lot smaller.
0:15 Nate and Kally over at The King of Random have shown that melting a magnet permanently negates its magnetic properties. So I'm interested to see how it goes the other way around.
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.
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
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.
Considering scientist is in your name I would have thought that you would have kown that when iron reaches a certain temperature (Before its a liquid) it becomes non-magnetic. I know this because testing iron with a magnet is the common procedure for checking if iron is ready for heat treatment when i'm forging tools
Why are you saying you're irrationality frustrated? You gave a clearly understandable rational reason. Why are you being irrational in thinking you're irrationally frustrated?
EDIT: if you knew that metal wasn't magnetic after a point why the hell did you make the excuse of trying to make ferro fluid in shape? You'd been better off trying to suspend iron fragments in a resin and curing it attached to a magnet.
haha i like how he went from the giant magnet to a smaller one for direct contact with molten metal as to nit ruin the large one. i have many magnets and the one that size that i have is called the death magnet by the company.
I've tried to watch his videos multiple times but I always bail after that line. Just sounds so incredibly lame. That intro would only work if he was obviously being sarcastic.
You do realize that molten metal has completely different magnetic properties? Once past the Curie point of the metal, you change its intrinsic magnetization, without attracting or repelling it.
I was about to post the exact same thing, but waited, and was happy to see that it was addressed later on in the video. But this really is something he should have already known, and his comments in the beginning about hoping to get ferrofluid-like iron sculptures makes it seem like he did not.
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.
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. I think two magnets would have worked better, but still. That is how most magnets are made, although usually it is done with an electromagnetic field.
+bassisku good observation I noticed that as well. And it's definitely not a neodymium magnet because it would be extremely expensive and much more magnetic.
+longshot7601 Not really, you could say he did his part as a scientist by doing the experiment and ended up confirming that things don't act as magnets when they're molten.
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.
+Arelias yes it is, but you quickly learn what is OK to pickup, what to avoid, and how large the magnetic field is. 800 lbs is the force on a flat metal surface, those iron bits only had a force of like 1lb
Also, magnetic fields are subject to the inverse-square rule; double the distance from the source, and you experience only a quarter of the force. 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.
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.
+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
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.
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.
But... if you pass a strong electric current through the liquid metal, then you could influence the melt with a magnet. Some molten metals can be pumped in this manner.
For everyone bullcrapping about this video, respect that he put time, effort and money into it. It’s not only for you. Do it urself and stop complaining!
Sorry, but these videos get less and less interesting. "what happens when we melt iron, it loses its magnetic properties, and we put it next to a magnet?". The interesting projects seem to be gone nowadays.
***** Fair enough, but my point stands. Right now it seems all we do is melt stuff and toss it into/onto other stuff. Stuff like the propane rifle. The building science, the project science.
I couldn't disagree more strongly. This is one of the few "fun dicking around with science" channels I know of that often posts negative results. And that's the reality of science! Very often, nothing interesting happens.
+Wolftiger01 :D It shouldn't destroy anything but the speaker, because a iPad uses flash storage, not like an hdd which uses magnetic driver heads to store data
+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.
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...
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
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
@@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.

I thought metal (when heated high enough) lost magnetism.
It does
Ohhhh I'm smart as shit lol
Nah jk I watch a lot of UA-cam is all
It does, it's called the Curie Temperature or Curie point.
Congrats, you guys payed attention to the video.
fill your pool with melted chocholate then put liquid nitrogen on it :D
YESSSSSSSS
yeeeeeeeeeeeees
Just get a bunch of chocolate in the pool on a hot summer day :)
XenoGamer it was for fun
just making things clear here
i think ill continue to come back and watch your videos, good stuff.
Thanks mike! See you around.
why the hell did he put his hand between the magnet and the iron? hahaha :')
That's what I wondered. He is so awfuly uncareful in every of his videos
i guess he gotta fall on his nose hard before he gets some common sense
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.
because it would have been very difficult to remove all the microscopical iron bits from the magnet. That thing is pretty strong.
You use a board for that, not your hand.
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. I think two magnets would have worked better, but still. That is how most magnets are made, although usually it is done with an electromagnetic field.
the magnet got allot smaller i dont think it was the same magnet
sneaky
it broke
A $150 magnet is cheaper to destroy than the $500 one.
+chieftain200880 ya don't say
what a phony
10 years later, Kevin renames his channel from "Backyard Scientist" to "Scientist"
Never EVER. Put your hand between a strong magnet and a magnetic material. Ppl have lost their hands from that before
It became small
+RickTGM I'm saving the big one for something else!
You should be a magician or a sleight of hand artist
+kush Lol
lmao i was wondering if anyone else noticed
Don't believe the ads, there's no way to make it bigger.
3:55 a cool magnet goes to waste :(
i was right :( sheeit
He used a cheaper magnet, it's not the same.
+bassisku yeah he thinks we dont know it it looks so small tho
+bassisku good observation I noticed that as well. And it's definitely not a neodymium magnet because it would be extremely expensive and much more magnetic.
Now it's a hot magnet!
If nothing else, a really good example of Electronic Thermal Breakdown.
iron becomes non magnetic after a certain tempature
did you even watch the video?
It does?
I think he's guessing what would happen before he saw
Yep. That's the Curie point. I'm surprised that not more comments are about this.
EDIT: just watched the Video, never mind.
ElectroBlood yea, i commented before watching the rest as well lol
I thought molten iron was nonmagnetic.
It is
Yes. It is. Thus there was no reason to destroy his magnet.
He switched magnets anyway
Yep. The 'scientist' title part of this channel's name is a misnomer.
+longshot7601 Not really, you could say he did his part as a scientist by doing the experiment and ended up confirming that things don't act as magnets when they're molten.
MOLTEN COREEEEEE!
play of the game.
+BBSHOCKZ that is a hotest thing ever
+AdamTDM Gaming what is?
+BBSHOCKZ ITS THE MOLTEN CORE HOTEST THING EVER
are you referring to the Earth's core?
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.
It's so hard to get metal shavings off magnets let alone this one.
use duct tape
You're a fucking genius, i've been trying to figure out how to pull off flecks of metal from my magnet, and you just answered it, thanks :P
Brilliant.
+Mr couchpotato thank you so much man. My welding magnets were covered.
You are a hero!
Picking up stuff with a neodymium magnet with your hand in the way? Isn't it like... dangerous?
+Arelias yes it is, but you quickly learn what is OK to pickup, what to avoid, and how large the magnetic field is.
800 lbs is the force on a flat metal surface, those iron bits only had a force of like 1lb
+TheBackyardScientist can you shoot aluminium bullets in a fish tank vs molten salt bullets in your next video
Also, magnetic fields are subject to the inverse-square rule; double the distance from the source, and you experience only a quarter of the force. 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.
+Ausogiea fare point
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.
I like how you just do some high heat stuff right on the grass.
Thank you for sharing your experiment in this video! Expensive magnet, though.
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
+Definitely Not B8ing I must've missed that lesson but I was thinking spinning molten metal makes a magnetic field so...
+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
youtube tought me that
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.
I'm sure he knew that. The point of this video was to prove that point through experimentation.
I wonder, a smart guy like you didn't know of the curie point before the experiment?
He genuinely seemed sad after his magnet got ruined
I experimented as a young man , You are doing good. Be safe with this stuff.
I think as molten ,the magnetic properties change. The molten iron show very little attraction or reflection.
you should collab with grant Thomas
GAMINGHOUR omg I love grant thompson, he is slowly becoming primitive technology though.
whatttttttt grant Thomas OR Grant Thompson
Who the hell is Grant Thomas?
steel and iron loose their magnetism attraction at about 1800 degrees Fahrenheit
Ok yeah he explained that after I said that^ so yeah
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.
But... if you pass a strong electric current through the liquid metal, then you could influence the melt with a magnet.
Some molten metals can be pumped in this manner.
Awesome science bro... I love your videos
Does metal not become non magnetic after a certain temperature? (Metal=iron, steel)
Oh, i got to that part :))
ya and magnets get demagitized with extreme heat
😆😆😆
please don't try to correct people incorrectly, that isn't a double negative, what he said makes sense.
+simontay1984 im sure he meant " doesn't metal become non magnetic. that way its not double negative. also, English isnt everyones native language,
Wouldn't the high temperature demagnetise the magnet suddenly?
Never mind lol
" oooh that really hurt" ....wear the damn protective equipment
For everyone bullcrapping about this video, respect that he put time, effort and money into it. It’s not only for you. Do it urself and stop complaining!
This is the first time I've seen you actually get hurt doing this crazy stuff you do lol I'm surprised it didn't happen sooner lol poor hand :(
try it with 2 N52 magnets of decent size smashing into each other and make sure you have no body parts in between. (Hint they shatter)
It didn't look like the same magnet from the beginning man... false?
"I don't want to ruin this one right away" I swear this composition of words mean something.. I just can't put my finger on it..
Yeah but he said it like he was going to anyway and didn't say anything about using a new magnet.
Well... I really don't care anyway... It was great
some might call that a lie. Leading someone to believe one thing and then doing another............ just sayin
umm you do know that metal loses its magnetism at melting temperature
He did say multiple 🙄🙄
Yeah you know how you're putting your hand between a big rare earth magnet and melted iron...well don't do that!!!
Sorry, but these videos get less and less interesting. "what happens when we melt iron, it loses its magnetic properties, and we put it next to a magnet?". The interesting projects seem to be gone nowadays.
+OnlyNeedJuan Gaming not everybody knows that.. in fact I learned that myself for this video!
***** Fair enough, but my point stands. Right now it seems all we do is melt stuff and toss it into/onto other stuff. Stuff like the propane rifle. The building science, the project science.
I didn't know that until I started blacksmithing. Not everyone knows
I couldn't disagree more strongly. This is one of the few "fun dicking around with science" channels I know of that often posts negative results. And that's the reality of science! Very often, nothing interesting happens.
+TheBackyardScientist do you have a snapchat?
I'm all for a different magnet. Just sounded like he was trying to say he destroyed "the" magnet. All Gucci, I just like transparency.
I literally enjoyed the video not because I randomly approaches but because I search for it and I got here.
Funny, suddenly that magnet got smaller
+Casey Urquhart I couldn't break the 4inch it's too expensive and cool so I bought a 2inch also!
And who can blame you -- we all knew the end results were not going to be fantastic.
he actually put a smaller magnet into the bowl.
He did say he didn't want to destroy it...
I noticed too
It's because he didn't want to destroy the bigger magnet
i wonder what would happen if you take an iphone next to that huge magnet .. oh wait wrong channel ..
+Wolftiger01 :D It shouldn't destroy anything but the speaker, because a iPad uses flash storage, not like an hdd which uses magnetic driver heads to store data
+Wolftiger01 :D BS, a iPad cover has Magnus inside so when you close to cover the iPad will turn off.
+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.
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...
+Monkeysrock
I didn't consider that.
If all the components are secure in the iPad. I would think it would be fine.
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
Good job copy and pasting this from the internet
@@richardthomas4910 lol thanks, but I learned this on college. Have a good day
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.
superconductor magnets.
Ever heard of a mobius strip
A magnet would lose its magnet ivory if it got too hot or too cold
Nothing will happen but a dead magnet.
Yup. Thought so.
+theLuigiFan0007 lol ur hypothesis then the actual reaction
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
Molten iron has very faint to no magnetic properties ... every high-schooler knows it
You would be surprised.
i havent leared that in chem yet
He already knew he was just demonstrating what will happen then explaining why it happens.
R.I.P magnet. Your life was used for entertaining scientific research. May you never be forgotten.
Also, that finger cut...ouch.
Did anybody notice that he changed magnets at the end 😂😂😂😂
Liquid iron doesn't have Magnetic properties! Ffs dude
did you uh... watch the entire video?
he makes these for us not for him
You mean molten because if you make iron into a liquid from metal shavings it is magnetic
@@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.
I think the magnit will spark like a wildfire
i failed science in high school but this guy makes it seem fun
substance loose their magnetic polarity when heated
