Magnetic interactions

  1. Mar 10, 2007 #1
    1. The problem statement, all variables and given/known data
    A magnet is hung by a string and then placed near a wire as shown. When the switch is closed, the magnet rotates such that the ends of the magnet move as indicated by the arrows. At the instant the switch is closed determine:
    a) the direction of the current through the wire segment nearest the magnet.
    b) the direction of the net force exerted by the magnet on the wire segment at the instant that the magnet is in the position shown.

    2. Relevant equations
    Right hand rule.

    3. The attempt at a solution
    a) The current will move in a clockwise direction in the perspective view because Not sure about this... Not quite good about right hand rule
    b) Into the page. Not sure about this either...
