A nonconducting ring of radius R is uniformly charged with a positive charge Q. The ring rotates at a constant angular speed ω about an axis through its center, perpendicular to the plane of the ring. a) What is the magnitude of the magnetic field on the axis of the ring a distance R from its center? b)Determine the magnetic moment of the ring.
