Website Detail Page

published by the Exploratorium
This site from the Exploratorium you'll find a simple demonstration of the interaction between a moving magnet and its induced electromagnetic field.  As the magnet is dropped down a metallic tube, it induces eddy currents that oppose its fall--an application of Lenz's Law.  The site contains a materials list, basic procedures for the activity, and an explanation of what happens in terms of the electric and magnetic fields produced.
