Its interesting to see a magnetic field at work.
(TruthSeekerDaily) When a magnet is dropped down a conducting copper pipe, it feels a resistive force (assuming that magnets have feelings). 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. Knowledge = Power. - See more at: http://truthseekerdaily.com/2014/01/here-is-what-happens-when-a-magnet-is-dropped-through-a-copper-pipe-wvideo/#sthash.xfu6EV4L.dpuf
