Also interesting but not particularly useful.

Cool and useful too if you happen to be teaching electromagnetic induction.

When a conductor sees a changing magnetic field, a current is induced in the conductor. The current induced in the conductor creates a magnetic field.

In this case the falling magnet creates a changing magnetic field (because it is moving). The induced current creates an opposite magnetic field which produces a force on the magnet opposite its direction of motion.

I'll never forget the freshman Physics lecture at LSU when the professor pronounced "Mother Nature is a B****" to help us remember.

There are applications of electromagnetic induction to fishing. Stay tuned ...
