60. (a) The period of rotation is T= 2π/ωand in this time all the charge passes any fixed point near the ring. The average current is i = q/T = q/2πand the magnitude of the magnetic dipole moment is µ===iAqrqr21222ππ. (b) We curl the fingers of our right hand in the direction of rotation. Since the charge is
