Demonstrates: Lenz's Law, Faraday's Law |
Description: When a non-magnet is dropped down a copper tube, it falls freely. When a strong magnet is dropped down the same tube, currents are induced in the tube. The magnetic field of the induced currents oppose the field of the magnet, slowing it down. The magnet takes several seconds to drop through the tube. Viewed from the top, the magnet seems to float down.
