When a loop of current-carrying wire turns continuously in a magnetic field, a is created.?

The correct answer is torque.

Explanation:

When a loop of current carrying wire turns continuously in a magnetic field then torque will act on the loop. The loop tends to rotate such that its normal becomes aligned with magnetic field. Torque is a force which rotate the object about an axis.

Torque depends on the orientation of normal to the coil to the direction of the magnetic field.

Therefore, when a loop of current-carrying wire turns continuously in a magnetic field, torque is created.
