Question

A 0.04 m² rectangular loop consists of 80 turns and carries a current of I = 5.2A. A 2.6-T magnetic field is directed perpendicular to the plane of the loop. If the loop is free to rotate about an axis parallel to the plane of the loop and passes during its center, decide the magnitude of the net torque exerted on the loop.
