Question

A circular coil of 25 turns and radius 6 cm, carrying a current
of 10 A, is suspended vertically in a uniform magnetic field of
magnitude 1 2 T The field lines run horizontally in the plane of
the coil Calculate the force and torque on the coil due to the
magnetic field In which direction, should a balancing
torque be applied to prevent the coil from turning?
