    Magnetic fields and electrical current.

    I have this question here that I'm having a little difficulty working out, I can't quite figure out if I'm correct.

    The question has multiple parts, most of which I have worked out, I'm just making sure I have my facts down right.
    ------------------------------------
    The illustration below shows a current carrying wire between magnetic poles. The arrows in the picture show the direction of the current.

    P1):
    In the illustration, will side x be forced up, turning out of the page, or down, turning into the page?

    A1):
    Side x would be forced down into the page.(I think)

    P2):
    How far will the wire rotate before it stops? Why?

    A2):
    It should rotate until it is perpendicular with the magnetic field.(Not too sure about this one.)

    P3):
    How could you cause the wire in the illustration to continue to rotate after it stops?

    A3):
    reverse the current at every half turn.

    Thank you!
