(a)The magnetic moment of a macroscopic body is defined as fv Mdr. Prove the relationship [ Mdr = 1 Femdr + Fo m da where S is the surface bounding V. [Hint: Refer to the similar problem involving polarization P] (b)A permanent magnet in the shape of a sphere of radius R has uniform magnetization Mo in the direction of the polar axis. determine teh magnetic moment of the magnet from both the right and left sides of the equation in part (a).
