Question: A circular loop of wire with mass M carries a current I in a uniform magnetic field. It is initially in equilibrium with its magnetic

A circular loop of wire with mass M carries a current I in a uniform magnetic field. It is initially in equilibrium with its magnetic moment vector aligned with the magnetic field. The loop is given a small twist about a diameter and then released. What is the period of the motion? (Assume that the only torque exerted on the loop is due to the magnetic field.)
