Slip rings maintain constant contact with the same sides of the coil As one side of the coil moves up through the magnetic field, a potential difference is induced (created) in one direction.

The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B - The coil is at 90°. The coil is moving at 90° to the direction of the magnetic ...
