Neodymium magnets, copper plates, Plexiglas ring

Code Number: 5K20.39

Demo Title: Eddy Current Levitator

Condition: Excellent

Principle: Eddy Currents

Area of Study: Electricity & Magnetism

Equipment:

Neodymium magnets (large, 12 magnet neodymium stack), 4 inch diameter 4 and 6 cm thick copper plates, Plexiglas ring.

Procedure:

Place the big magnet between the plates inside the Plexiglas spacer. By varying the distance of the magnet stack from the top plate you should be able to get the big magnet to float between the two pieces of copper.
