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.

@joshuakrieger4398 4 года назад

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.

@joshuakrieger4398 4 года назад

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?

@realcygnus 4 года назад

surely

@Zomby_Woof 4 года назад

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.

I wonder, if you get a powerful-enough magnet, can its eddy currents do anything to a bullet?

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?

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.

The adults (both of us studied geology) spent about two hours collecting magnetite....

@cphVlwYa 4 года назад

@@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.

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!

@mylesharrison2455 4 года назад

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.

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.

@andypharo5116 Год назад

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.

@barkingbarker8291 4 года назад

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.

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.

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.

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.
