A circular coil of 200 turns and radius 10 cm is placed in uniform magnetic field of 0.5 T. Normal to the plane of coil. If the current in the coil is 3 A calculate total torque on the coil total force on the coil average force on each electron in the coil due to magnetic field. Assume the area of cross section of wire to be 10-5m2 and free electron density is 1029m3
