[SOLVED] hand rule application (dir of mag force) 1. The problem statement, all variables and given/known data You witness an experiment with a wire (a part of a circuit) and a horseshoe magnet. It begins with a wire laying on a table and passing through the mag field of the horseshoe magnet, but with no current passing through the wire. When the current is turned on, the wire experiences and upward force and as a result, jumps vertically out of the mag field. If the current in this experiment was flowing due north (ie, the hypothetical positive charges were flowing due north), in what direction was the magnetic field of the horseshoe magnet at the original location of the wire? a) north b) south c) towards the center of the earth d) away from the center of the earth e) west f) east 2. Relevant equations n/a 3. The attempt at a solution the test "answers" state: To create an upward force on a current going to the NORTH, the magnetic field through which the current is passing must point towards the WEST. I can apply the hand rule to a wire, but how do I apply it to the horseshoe magnet? This really confuses me.
