When a magnet moves near a conductor, it creates an electric current.

An electric current produces a magnetic field.

As a result, when a magnet moves near a non-magnetic conductor, it produces an electric current that, in turn, produces a magnetic field. The demonstrations at this table are related to magnets, and in particular, the temporary magnetic fields produced by eddy currents.

There are also demos of diamagnetic repulsion and homopolar motors.

"Gravity Is Optional" physics demonstrations at the March 2012,
GLMS-MC Gem/Mineral/Fossil Show.
