Question:
The total charge of an insulating disk of radius R=20 cm is q=5C. The charge Q is not evenly distributed on the surface of the disc, and the surface charge density is given by the expression alpha=Axr. Here A is a constant and r is the distance from the center of the disk. The disk rotates around the y-axis with an angular velocity of W=20 rad/s. Find the magnetic moment M of the disk.
