Magnetic moment

  1. May 3, 2005 #1
    Let's say we have a 4-sided loop. Is the magnetic moment different for each side?

    The magnetic moment is a property of the loop as a whole (m=I*a). Technically, you could get the contribution from each side to the total moment, but since each side is the same (I'm assuming), this will just be 1/4 of the total.

    What about the direction?

    Same direction, 1/4 the magnitude. Think about the symmetry.
