The magnet induced a current in the copper pipe, which in turn produced a magnetic field. The direction of this current then opposed the change in the magnet’s field, resulting in the magnet being repelled and thus falling more slowly. Neat.

I supose a magnet of the opposite polarity.

+Paul Spoerry What would happen if the copper pipe was instead a magnet, for instance a solenoid with a current running through it?
