A current-carrying, rectangular coil of wire is placed in a magnetic field. The magnitude of the torque on the coil is not dependent upon which one of the following quantities?

Question

Quizplus · Accepted Answer

The direction of the current in the loop determines the direction of the torque, but the magnitude of the torque depends only on the strength of the magnetic field and the geometry of the coil (length of sides, area, and orientation). Therefore, the magnitude of the torque is not dependent on the direction of the current in the loop.
