Let at any instant the normal to the plane of loop make an angle θ with the direction of magnetic field B and I be the current in the loop. We know that a force acts on a current carrying wire placed in a magnetic field. Therefore, each side of the loop will experience a force. The net force torque acting on the loop will be determined by the forced acting on all sides of the loop. Suppose that the forces on sides PQ,QR,RS and SP are
