Choose the corret option :
A rectangular coil of copper wires is rotated in a magnetic field . The direction of the induced current changes once in each ……

A

two rotations

B

one rotation

C

half rotation

D

one - fourth rotation .

Text Solution

Verified by Experts

The correct Answer is:
C
After each half rotation , the direction of motion of the two parallel sides of the coil (AB and CD) is reversed and so the direction of the induced current changes once in each half rotation .
