What is magnetic moment of a current loop?

A rectangular coil carrying current is placed in a uniform magnetic field in such a way that normal to the coil makes an angle theta with the direction of magnetic flux density. Find the magnitude of torque acting on the coil Define magnetic moment of a current loop.
