The figure shows a rectangular 20-turn coil of wire, of dimensions 10 cm by 9.6 cm. It carries a current of 3.5 A and is hinged along one long side. It is mounted in the x – Y plane, at angle 0 = 30 to the direction of a uniform magnetic field of magnitude 0.50T What is the torque acting on the coil about the hinge line in units of N.m? Hinge line
