Any other electrical engineers or physicists here? BTW, Lenz's law and how the eddy currents induced in the copper piping produce a resistive effect on the magnet's magnetic field.

To anyone wondering what they're looking at - magnetic fields, when they move through a conductive material, produce an electric current in that material. All electric currents also produce a magnetic field around them. So the magnet is falling through the tube, and the magnetic field of the magnet induces a current in the tube, which in turn produces its own magnetic field, which interacts with the magnet, slowing its fall.

Try it with a superconductive magnet and Chilled metal.... Its a bit cooler XD No pun intended

i notice that his hand jerks right after the slug falls out of the copper tube, does that mean that while the electromagnetism affects the slug that he is then holding the combined weight of the slug and the tube, or does the slug become "weightless" in perspective to the tube?

This can also be produced with aluminum. But you have to have a strong magnet, really.

I'm thumbing this just because I went on a 3 hour youtube spree on how to melt metal, and I think I might have discovered a new hobby.
