A circular coil in a galvanometer has 1500 turns, very closely wound, and a mean radius of 1.2 cm. The plane of the coil is held parallel to the uniform magnetic flux density of 0.5 T by a torsion wire. If a current of 10 A produces a deflection of 30?, what is the torsion constant or the restoring torque of the torsion wire per radian deflection?
