A wire loop is rotated in a uniform magnetic field about an an axis perpendicular to the field. The direction of the current induced in the loop reverses once each

A

quarter revolution

B

half revolution

C

full revolution

D

two revolutions

Text Solution

Verified by Experts

The correct Answer is:
B
It is because after every 1/2 revolution the current becomes zero and mode of change in flux changes therefter (If before the current becomes zero, the mode of flux change was from left to right then after the current becomes zero mode of flux change becomes right to left).
