- We've seen what happens to magnets when you heat them up, but what happens when you freeze them? They lose magnetism when they're heated up, so will the opposite happen when they are made cold? Does freezing magnets make them super charged?

Reducing temperature reduces resistivity, so the magnet is inducing stronger Eddy currents. The now opposing magnetic field is stronger, so the magnetic forces are stronger.
Yes, lower temperatures reduce the electrical resistance, since the atoms in the crystal lattice of the metal, e.g. copper vibrate less, this allowing the electrons to flow more easily. On a molecular level, temperature is defined by the kinetic energy of the atoms and molecules, at high temperatures they vibrate fast, getting in the way of electrons, creating what we know as electrical resistance.
Also, the Eddy currents work, because the change of a magnetic field creates an electric field, and vice versa, so the magnet passing by induces an electric field which in turn as its strength changes creates a magnetic field opposite to the magnet's, slowing the magnet down.
Since the strength of the counteracting magnet field is proportional to the speed of the magnet, an equilibrium ist between gravity and the magnet force slowing the magnet down occurs.
So, less electrical resistance means there is a stronger opposing magnetic field at lower speeds, that's why the magnet took longer to get to the bottom of the tube.
On a side note, light also is nothing else than a magnetic and an electric field constantly building up and on collapsing inducing the other, this the name electromagnetic wave

When you drop the magnet through the tube, does the tube get heavier? Like if you weigh the magnet and tube separately, does it weigh the same when the magnet is falling through the tube?
surely
Weight = mass * gravity
Mass isn't changing because nothing is being removed or added.
If you had a sufficiently sensitive scale you'd see a slight reduction in weight, but you'd be wrong.
You would have failed to account for the slightly reduced volume with the lower temp which means the objects displace less air, which has a non zero buoyant effect.
Sort of like when they were floating an aluminum foil boat in SF6.
To amplify the effect take a helium filled balloon and immerse it in ln2.
It will deflate to the point where it no longer displaced enough air to float until it warms up, expands and displaces more air.
Weight = mass * gravity in a vacuum.
@@Zomby_Woof I think he means more like the magnet is imparting its weight onto the tube to slow itself down and that force has to go somewhere

I wonder, if you get a powerful-enough magnet, can its eddy currents do anything to a bullet? I mean, lead may not be known for its conductivity, but it should still be affected if you make the magnetic field powerful enough. So I guess the real question is, how powerful and deep does a magnetic field have to be to dissipate enough energy from a bullet that it does no damage?

An experiment we did at my mothers house for the kids: Put the neodymium magnet in a zip-top bag and run play sand across it. The magnet pulls out the magnetite (black grains) in the sand. You need a pretty strong magnet for this; we tried a few, and the neodymium worked best. The kids thought it was cool for about ten seconds. The adults (both of us studied geology) spent about two hours collecting magnetite....

Hello Pressman here, explanation for why the magnet slid on one side of the paper but not the other is. When the paper is made at the paper mill the paper is strained through a wire mesh and is pressed by felt on the other side. so one side of the paper has a slight texture of the wire mesh while the other side is smoother from the felt. You can observe this on most every kind of paper with a magnifying glass. It is also a factor of how much silicone/anti-static the pressman applied during the run as it does not always flash off before packaging.
I think their “50%” stronger comment neglects that most forces like that have an r^2 kind of reduction with distance. So 50% more range implies a much greater increase in strength or power.
🤯
I know you're saying that it would be 2.25 times stronger but the reality is that r^2 has no application in that particular test.
BIG BRAIN
@@namansingla2975 No, Drew Stevenson is right. By saying the magnet is x time stronger you're referring to the magnitude of the magnetic field vector at a given point. However, in the test we're not measuring the change in the field strength, we're measuring the point at which the force applied by the magnetic field times the coefficient of friction between the magnet and paper is equal to the force of gravity. As such, it is only fair to say the strength has increased by 50% if the filed decreases linearly - which it does not.
They do know that the effect of super-cooling magnets has been known for years and is taught at Middle School where I live in the UK? Super-cooled magnets have been used in the Large Hadron Collider among many others.
What happens when you pour liquid nitrogen on a head of letuce and then set it on fire or put it in a microwave
I’ve been wanting to see this! Thank you!
0:21 I C (P) wut u did there
@Jonathan Meyer Listen to "Miracles" by Insane Clown Posse and you will get it
You got the aluminum to enter (or get really close to) the superconducting regime, so the eddy currents were stronger and therefore the resultant opposing magnetic field was stronger (same with the copper ingot). This is why supercooling is used/needed for magnetic levitation. Thanks for an awesome episode!
8:13
That happens becaus e of the better electrical conductivity at low temperatures. So the electrons can move better and form a stronger Magnetic field.
The reason why this effect is stronger when you increase the speed of the magnet is, that there are stronger changes in the magnetic field. That leads to a stronger induced magnetic field of the copper.

Well, this the reason that the magnets in an MRI are cooled by liquid helium:
Stronger magnetic field.
now you just need a magnetic track and a super conductor to make it hover along it, even upside down. (best example is to make a mobius strip lined with magnets)
• 3:33 - Contactless magnetic/eddy-current brakes are used in various applications like roller-coasters, trains, elevators, and anywhere else where a large mass or high-speed (i.e., high force) needs to be stopped, as well as in places with high risk of fire, because frictional braking would create sparks and wear down the brakes rapidly.
• 5:14 - Sometimes. I tried getting a dog, but that just made it worse. 🤦
• 8:20 - It's kind of like a Goa'uld energy-shield; the repulsive force is directly proportional to the incoming energy.
• 11:27 - You're not making the magnet stronger; the cold is just making it harder for the atoms to align to the magnetic field.
I think the difference between the time for the magnet falling through a cold tube and a room temperature tube is to do with the fact that electrical resistance increases as temperature increases, this means that the eddy currents generated to be bigger (as have a bigger current and a smaller voltage as V=I*R.) this means that the force generated is bigger (since F=B*I*L). This is also the same principle for the magnet swinging towards the copper.
freeze a superconductor in liquid nitrogen then get a neodymium magnet and try get it to float
You need a type 2 superconductor for that. The flux pinning effect of the type 2 superconductors causes it to float in place.
The reason why you got better results from cooling the aluminium and copper down is because when you cool something that creates the eddie currents when a magnet moves near it to liquid nitrogen tempratures it amplifies the eddie currents they make and makes them much stronger then before as the electrons the material has basically zero electric resistance or something like that. The Action Lab explains it better in a video about superconducticity than I just did if you want to check it out.

Wow. Quarantine got me early. first view
Magnets have a preferred temperature where they work best ~120-130 below zero for neodymium magnets. Beyond that, it starts to decrease in effectiveness again. Try using dry ice rather than liquid nitrogen.
The freezing of a conductor using liquid nitrogen is how they make superconductors. Normally magnetic objects lose their magnetic nature, but supercooled conductors convey currents much more effectively.

It should still work, but might cause problems. If cold temperatures lower electrical resistance, then super freezing an appliance cable may result in more energy entering the appliance and damaging it. I honestly dont know, though.

I found this actually searching for experiments on the effects of magnetic fields on ice (especially sea ice). For anyone who's curious, my experiments strongly suggest that when salt water freezes under an applied magnetic field (i.e. stronger in magnitude than ambient MF) it does so at a higher temperature. If you then study "magnetised ice" as it melts, the meltwater it creates is warmer but the ice itself is colder than those from "non-magnetised" ice.
My experiments and those of other scientists also show that magnetic fields also effect other properties of seawater such as its salinity, solubility of CO2, evaporation rates, viscosity and thermal conductivity.
There are videos of tap water (non-salinated) being moved by a strong neodymium magnet on YT also you might want to try creating an icicle (I did so by freezing water inside a straw with its ends sealed with tape). Suspend from a thin thread (to reduce torsional effects) the icicle so it balances horizontally, wait for any twists in the thread to work themselves out then try slowly approaching one end with a strong magnet. You will gradually see the icicle start to turn away from it (water is slightly diamagnetic). If you move the magnet in a "pulsating" fashion in the vicinity of one end you will see an even stronger repulsion (the movement of the magnet is creating stronger induction effects). Test with a similar block of non-magnetic metal if you suspect it might just be air currents moving the icicle.
I'm early again wtf is corona doing to me 🧐😤
Getting you drunk
@@emmawilliams9904 no not exactly my point😅
Magnetic fields decay in strength at an exponential rate so that gap, although small, represents a HUGE change in strength between warm and cold
Is Kiwi co the new "Raid shadow legends".
most magnets don't mind the cold. In fact, some may perform better when the temperature drops. That's because the atoms that comprise magnets vibrate more slowly and less randomly when cold. The result is a better alignment of the atoms that generates the magnetic field, boosting its strength.
"such a cool result to see" I guess the pun isn't intended? Or maybe not even noticed?
Magnets. How do they work? Nice Insane Clown Posse reference.
I love magnets because they are so permanent (for the most part). I have hundreds of magnets from computer hard drives. Small ceramic magnet attached to a metal plate. But if you remove the metal plate, they get weaker for some reason.
I expect The King of Random to have random RUclipsrs in their studio/kitchen.
I think the reason it still worked was the fact that by freezing it, you just made it superconductive, like the lexus hoverboard.
"....magnets, how do they work?"
(Wondering if they know that's an ICP reference)
So i have seen this kind of occurence before. Its the same principle as the lev trains. A magnet that is super cooled creates a super conductor effect. Not sure if thats the correct name. You can even make a track for it and it will move along it as long as the magnet is cold. Its really fun to watch.
Callis new hair color looks absolutely amazing
Here's an idea, if you smash up the magnet into little tiny pieces so it is almost as fine as a power then try putting that through a copper tube or try doing other things to it.
The reason that cooling the conductor is more effective than cooling the magnet is that all conductors are electric superconductors at absolute zero. This means that the colder the conductor is, the less resistance the electrons flow with in it. Since the induced magnetic field depends on the flow of the electrons, the field is stronger when the electrons flow with the least resistance. This is why superconductor materials need to be cold to function.
it makes sense the colder something is the slower it moves, so with the metal being cold it causes the magnetic fields to be a bit stronger. With the magnet being cold the atoms in it are moving much slower and not as random. creating a more aligned atomic structure thus the stronger magnetic field.
It's nice to see content on RUclips that isn't a livestream.
Calli is looking extra fabulous for quarantine while the rest of us can barely bother to put pants on... Respect👊🏻
Very cold not-magnets can be suspended in place in magnetic fields, which is cool.
But if you have a strip of magnets it can move along them while maintaining the orientation you put it in, it's definitely worth trying for anyone with access to liquid nitrogen.
Try to have many magnets inside a tube, and push perfectly the first magnet so to ring a bell at the end, must be 1 meter or more the tube. Where one magnet hits the other, and no less than a magnet distance between them. Before you do the experiment, you must do an equation and find out the perfect push beforehand... Sorry i raised the steak ;)
You can make a hoverboard by putting magnets on the bottom of a skateboard deck and "ride" on big copper sheets. A video was made about that and its really cool

That's why parents want kids watching ya'll lol
Some (if not all) MRIs (Magnetic Resonance Imaging) use supercooled magnets to get strong. If something magnetic gets inside or close to the machine, the only way to retrieve that item is evacuating the coolant. Destroying (at least temporarily) the MRI machine. Plenty of videos on RUclips of office chairs vs MRIs lol.
Not exactly. They’re using liquid helium to cool type 1 superconductors down into their superconducting state. They then use an electric current to produce the magnet field.
Might try marking a piece that is slick side up and use that one sheet as a control sheet for more of a consistent read
i suggested this so many times!!!
I suggest a video made by The Action Lab on this topic. He did this with even bigger magnets and even managed to visualize Quantum Entanglement with it! Seriously two magnets were Quantum entangled with each other and one was just floating on top of the other like it was hanging on a string.
I can't be the only one that wanted to see Nate launch the magnet off the wooden skewer 'rail gun" style. The power of repulsion... much like my dating life. haha :(

I was wondering if you could check out if it would be possible to use liquid nitrogen to cool down forged metal instead of using either oil or water, would be quite interesting to see how it would influence the grain structure of the forged metal, since it's highly not recommended to use water to cool it down as it might make the grain structure more brittle, would be cool to see if liquid nitrogen would make it even more brittle... Also could be fun to see the reaction of pouring melted metal into it as well! And yeah, I'm a big fan of Forged in Fire!
Im guessing because metal contracts with cold and expands with heat, the magnetic waves are closer in proximity with the cold as opposed to heat which would spread the metal and thus magnetic concentration apart.
cool you made super conductor
Action Lab would be proud
