Consider the situation given in figure. The wire AB is slide on the fixed rails with a constant velocity. If the wire AB is replaced by a semicircular wire, the magnitude of the induced current will

A

decrease

B

increase

C

increase or decrease depending on whether the semicircle bulges towards the resistance or away from it

D

remain the same.

Text Solution

Verified by Experts
