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

A

increase

B

remain the same

C

decrease

D

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

Text Solution

Verified by Experts

The correct Answer is:
B
As we have to consider the length perpendicular to velocity vector and magnetic field vector independent of shape and length of wire, the perpendicular length between two wires is constant hence value of induced current will remain constant.
