A circular coil of 30 turns and radius 8.0 cm carrying a current of 6.0 A is suspended vertically in a uniform horizontal magnetic field of magnitude 1.0 T. The field lines make an angle of `60^@` with the normal of the coil. Calculate the magnitude of the counter torque that must be applied to prevent the coil from turning.
