Magnets and Electricity

  1. Jun 5, 2008 #1
    I have read in quite a few places that you can pass a wire through a magnetic field and this will produce electricity. Does the polarity of the magnet have any effect on this or is it just the fact that it is a magnetic field? To be a little more specific, if you had a wire setup next to an electromagnet attached to AC power would the constant polarity change create electricity?

    You're question is worded oddly, but I'll answer what I think you are asking. An electric current is produced by a change in the magnetic flux enclosed by a loop of wire (a closed circuit). The polarity of field is not the important point, but rather whether the flux increases or decreases. Accordingly, a loop in an AC field will carry an AC current.
