Repeat Exercise 22.48, but with the loop lying flat on the ground with its current circulating counterclockwise (when viewed from above) in a location where the Earth’s field is north, but at an angle 45.0∘
below the horizontal and with a
strength of 6.00×10−5 T
(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?
