Question about electromagnet induction in a coill.

  1. Apr 21, 2008 #1
    If you have a bar magnet in a coil and rotate it sideways (poles on the side of the magnet) does it produce an alternating current and do the number of turns in the coil affect this, and if you move a magnet through a coil one way and then the other, does it produce an ac current?

    If you are representing your bar magnet as a perfect magnetic dipole (which is a valid representation in some cases), then your answer is no, since the field of a perfect magnetic dipole has cylindrical symmetry and will be unchanged when rotated about it's axis.

    What if the magnet was facing the other way?
