This Is What Happens When A Magnet Is Dropped Through A Copper Pipe
The Mind Unleashed

When a magnet is dropped down a conducting copper pipe, it feels a resistive force (assuming that magnets have feelings).

The falling magnet induces a current in the copper pipe and, by Lenz’s Law, the current creates a magnetic field that opposes the changing field of the falling magnet. Thus, the magnet is “repelled” and falls more slowly.

The pipe would be really cool, but you can get the idea on a flat surface. The magnet test is supposedly a test for silver coins. If you tip a silver coin at a 45 degree angle and slide a rare earth magnet down the coin face, it will slowly slide at a speed far less that one would expect the magnet to slide. I say "supposedly" because, although this works, it will do the same thing with brass or copper, so.... One can reeeelly get the idea if you have a brass or copper tray. Slide the RE magnet down and watch it "defy" gravity. Amaze your friends. Get girls. See through clothes x-ray powers.... order yours today!
