Question

A rectangular coil of a copper wire is rotated in a magnetic field. The direction of the induced current in the coil changes after:

• A. every one-fourth rotation
• B. every half rotation
• C. every one rotation
• D. every two rotations

Hint:

The induced current in a rotating coil changes direction every full rotation.

Answer 1

The Correct Option is C

The direction of the induced current changes after one full rotation (360°), i.e., every one rotation.
