- Magnetizing an Allen wrench...
If you don't subscribe and like this video, you may or may not regret it. I'll get a hold of every Allen wrench of yours I can find, and I'll magnetize every one of them. Lets not take it this far. You know what to do.
"Then we will hit it with a hammer" science at its best
Yup! In the old days ships would become magnetised through all the hammering of rivets etc. In early WW2, the Germans exploited this by designing magnetic mines which puzzled the British at the beginning as ships suddenly sank without hitting anything the damage being compared to a gigantic hammer-blow! Once scientists realised what was happening, big ships were fitted with de-gaussing coils while smaller vessels that could not produce the necessary electrical energy were 'wiped' to demagnetise them.

The most underrated video by far hands down
I vaguely remember an experiment in grade school, wherin we magnetized a pair of Crayola scizzors by rubbing a magnet along the blades. I remember my pair kept their magnetism pretty well for a year or so afterwards. Neat stuff.
You're very interesting to watch, I also like that you explain the process and why it happens. Thank you
This is asmr to me so well explained and detailed feels like an ancient alchemist instructor, nice video bro.
Maybe I'm "romanticizing" my youth but I seem to remember my dad showing me how to magnetize a screwdriver by simply holding it vertically pointing towards the ground and smacking it with a hammer. Of course I can't bother myself to go to the garage and try it before posting this 😂 he could have of course just been screwing with his young impressionable son 😉 and it was already magnetic
The way you make a magnet this way is to have a slightly thinner wire gauge at the end. So it'll actually burn out like a fuse when it reaches the peak of the current.
And then disconnect it from the electrical source. That way, you can use AC. Currand I'll break it at the peak i'm one of the peaks
why do you hit it with a hameer while magnetizing it? is it to align the orbitals in that direction?
Yeah, pretty much. The domains can align with the magnetic field on their own, but giving it a couple of taps with the hammer helps knock more of the domains out of their oreintion. You can also heat it up then cool it down in the presence of a magnetic field to achieve the same effect.
I do understand why hitting with a hammer makes the magnet stop working.
But why does hitting it in the presense of a magnet make it magnatised? Like, what does the hammer change from it just being in a presence of a field?
It jiggles the atoms around a bit and makes it easier for the domains to reorient themselves and align with the field. They'd want to stay in place otherwise. But I could be wrong. Some people suggested hitting it with a hammer was unnecessary.
Like he said, it allows the atoms just a bit more freedom to reorientate themselves. They’re experiencing a magnetic pull towards the magnetic field, so when they stop being shaken and settle back in, a higher % will be facing the desired way and magnetize it.
Imagine you have a jar of rocks and sand. You want all the rocks at the bottom of the jar, but the sand is in the way. If you shake the jar up, you’re going to notice some of the rocks ended up on the bottom in place of the sand, but not all of them. It’s the same for the magnet, except instead of rocks on the bottom you want them to rotate.
You can increase the effectiveness by getting more of them to face the same way, but that gets harder the stronger you want it.
@nicksgmail9663 so are you implying that the longer you tap it with a hammer, the stronger it's magnetism?
@@visualmunchables Consequently it seems to me high amplitude vibrations would work better than a hammer
Seems to me hexagonal wrenches aka Allen keys are a good source of magnet steel since these come hardened. The down side is if we want a few small mgnets from one key we need to find some way of cutting/grinding. Alternatively, we might used half-hard steel rod (silver steel in England), cut, harden by heating and rapidly quenching then magnetising. Keep up the good work!
Im gon need this for the future 🗣🔥
Great video, I learned a lot thank you!
Glad you enjoyed it!
Bro literally beat the magnetism into it
so if i hit a neodymium magnet with a hammer it will lose its magnetism.
Nice video shot, thanks for sharing with us, well done :)
Maybe you know and if so could you please tell me…. I’ve a magnetic charging port on a device and a magnetic charger. Both have two magnets of opposite polarisation. The device has lost one of its magnets and I was wondering how to replace it please? I can’t find replacement magnets for these types of charges online, I don’t know if I can use non magnetised metal, whether it will still allow the current to flow and the device to charge, whether it won’t work at all or whether it’ll burst into flames and whatever solution I use it’s going to be too small for me to hold on to test so I’m going to have to go straight for the superglue or whatever glue you use for electrical components.
Any ideas? Please?
And you discharge current on the tap/ remove and make electricity???
So is there a way you could make something already magnetic slightly stringer with this technique?
Yes, as long as the magnet you use is stronger than the one you're trying to make stronger. But this will only work to a certain extent. The more aligned each of the atoms are with each other, the stronger the overall magnetic field will be, but once all atoms are aligned, you can't really go beyond that.
Bruh I loved this
For how long the allen rench remain magnatized after hitting it?
I have so many Allen wrenches, so I lost track of the magnetized one. But for a metal like that, at the size it is, you'll probably need to repeat every couple of weeks or so. It will probably get better and better overtime though as long as you repeat the process with the same polarity each time.
Curious as to where you got your periodic table with the picture from?
It's from Kurzgesagts merch store
You don't need the magnet to magnetize the steel bar. You can just point the steel bar magnetic north (and use the earth as a magnet), whack the end with a hammer and the bar turns into a magnet.
Please stay off the internet and don't comment for a while.
@@richardb8104 try it. We did it in elementary school.
The magnetism in the wrench seems to be very weak, how can it be made stronger?
A stronger magnet will do the trick! Also, using metals more pure than the wrench should work better. Another idea is to heat the wrench and let it cool down in the magnetic field while tapping it, but be sure not to heat the magnet. But that's just a theory.
Can you use this for magnetic induction
Sort of.
However, the strength of the magnetic field won't be enough to be useful.
can I get link for periodic table
Look up "Kurzgesagt shop", and ya should find it. It's a RUclipsr's merch.👍
Thanks I found
Can you do a socket like for a car
What metal can you use ?
As I said in the video, iron, cobalt, nickel, and gadolinium are the only metals that'll magnetize at room temperature.
@@SomethingAbtScience a terrible idea just came to mind: what if one were to be in the middle of the wilderness with very little outside magnetic interference and tried to tap metal into being a magnet make a generator based on that, create a stronger magnet based on a solenoid, put that new magnet in the same motor and repeat until they got a strong magnet?
Yes, possible @@harrymu148
I’m tryna find a way to increase fuel source.
I'm sure a motor powered by magnetic force is possible
I got interested in that 15min ago wtf.
Uh i saw that you can demagnetize a magnet with fire so the magnet can be stronger if he is in like..Ice ?
It won't necessarily make the magnetic field stronger, but cooling it down would make it slightly less susceptible to an impact demagnetizing it. Cooling it down causes the magnetic domains in the magnet to be more stable, and denser.
Thanks for the explanation !@@SomethingAbtScience
If you just RUB the strong magnet in ONE direction over and over it will magnetize that allan wrench better than that. Kind of like whittling wood motion or using a ferrocerium rod.
Thumbs up still.
This is for the same reason though at the end of the day. When you rub the two it’s still “hitting it” because it’s bumping along the edge many times we don’t see. It’s still wiggling the atoms and letting them orientate themselves towards the magnetic field, which is the purpose of hitting them.
The reason it seemingly worked better for you could be that the smaller bumps allow for better adjustments.
seriously?!? we just hit it with a hammer in presence of a magneting field?
we can make like infinite magnet generators. holy shit.
does this weaken magnetic field on the stronger magnet over time? or is it seriously this easy to make magnets?
@@l.e.u.m.a.s4218 The metal you turn into a magnet will not have nearly as strong of a magnetic field as the neodymium magnet or electromagnet you use.
But if you want really good results, I'd melt the metal or get it red hot and let it cool down in the presence of a magnetic field.
This will allow the magnetic domains which are trapped in the solid metallic lattice to re-orient themselves with the magnetic field while in a liquid or at least red hot state(idk the required temp). Then it solidifies while they're all aligned with the field if that makes sense.
The maximum magnetic field strength you can achieve is determined by the magnetic properties of the material you're magnetizing, not the external magnetic field you use to magnetize it.
beating with hammer unnecessary, just rub it on the magnet.
The effect isn't permanent if you don't realign the atoms... which is way more effective by beating the metal with a hammer.
He is explaining it with a piece of metal
Why would you post with a thumbnail of a wound wire if that isn't what you are going to do?
I didn't make a thumbnail for this video. When posting a video, youtube gives you 3 thumbnail options from frames of the video, I chose the most relevant one. Also, what's shown in the thumbnail is one way to make a permanent magnet, not just an electromagnet.
wait a minute.. what are you doing? not syncronice with the title bro!
I'm unsure why it would need to be synchronous with the title. But it does relate to the title if YOU'D wait a minute lol
Imagine if it charges up to 10k volts😅
1:48 how the heck did that work
Eat gadolinium
Very poor
Reminds me of our old television. Also four elements. Dad mom bro sister and me hhahha
