| Demonstration of Lenz Law |
 |
Moving metal past a magnet (or vice versa)
induces an electric current that acts as a
brake on the motion. Various metals have
different conductive properties and will fall
past magnets at different speeds. Some like
aluminum are very conductive, and others like
a nickel-zinc allow have bad conduction and
hardly slow at all. Tags : magnets lenz law magnetic braking |
