Multiple Choice
A flat circular wire loop of area 0.25 m2 carries a current of 5.0 A.This coil lies on a horizontal table with the current flowing in the counterclockwise direction when viewed from above.At this point,the earth's magnetic field is 1.2 × 10-5 T directed 60° below the horizontal.What is the magnitude of the torque that the earth's magnetic field exerts on this loop?
A) 2.5 × 10-6 N ∙ m
B) 5.0 × 10-6 N ∙ m
C) 7.5 × 10-6 N ∙ m
D) 1.0 × 10-5 N ∙ m
