(a) A 650-turn circular loop of radius 32.0 cm is vertical, with its axis on an east-west line. A current of 125 A circulates clockwise in the loop when viewed from the west. Earth’s field here is due north, parallel to the ground, with a strength of 3.2 × 10−5 T. What are the direction and magnitude of the torque on the loop? (b) Does this device have any practical applications as a motor? Explain.
