QUESTION:

Problem 48PE

(a) A 200-turn circular loop of radius 50.0 cm is vertical, with its axis on an east-west line. A current of 100 A circulates clockwise in the loop when viewed from the east. The Earth’s field here is due north, parallel to the ground, with a strength of 3.00×10−5 T . What are the direction and magnitude of the torque on the loop? (b) Does this device have any practical applications as a motor?
