Is it possible to temporarily reverse poles of permenant magnet using electrical currents

  1. Sep 30, 2014 #1
    Found one article saying it is possible to reverse poles of permenant magnet using coiled wire wrapped around magnet, but nothing about the possibility of temporarily reversing or even temporarily weakening the magnetic field.. if there are any magnetism connoisseurs out there..

    That's how the magnet factory in my town makes them permanently magnetized.

    An old fashioned soldering gun will reverse a hand compass.

    Try it. One experiment is worth a thousand expert opinions.
