Lenz's Law with Copper Pipe

A magnet is dropped down a conducting copper pipe and feels a resistive force.  The falling magent 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.
