SonOfTheGods Posted March 15, 2014 copper pipe and neodymium magnet    When a neodymium magnet is dropped down a conducting copper pipe, it feels a resistive force. The falling magnet induces a current in the copper pipe and, by Lenz’s Law, the current creates a magnetic field that opposes the changing field of the falling magnet. Thus, the magnet is “repelled” and falls more slowly.  3 Share this post Link to post Share on other sites
SonOfTheGods Posted March 15, 2014 http://en.wikipedia.org/wiki/Lenz%27s_law  An induced electromotive force (emf) always gives rise to a current whose magnetic field opposes the original change in magnetic flux. 1 Share this post Link to post Share on other sites
