Total: 60

A closely wound solenoid of 2000 turns and area of cross-section 1.5×10−4m2 carries a current of 2.0 A. It is suspended through its centre and perpendicular to its length, allowing it to turn in a horizontal plane in a uniform magnetic field 5×10−2T, making an angle of 30° with the axis of the solenoid. The torque on the solenoid will be

3×10−3N−m
1.5×10−3N−m
1.5×10−2N−m
3×10−2N−m
