A conductor is moving with the velocity ...

A conductor is moving with the velocity `v` in the magnetic field and induced current is `I`. If the velocity of conductor becomes double, the induced current will be

A

0.5 I

B

1.5 I

C

2 I

D

2.5 I

Text Solution

Verified by Experts

The correct Answer is:
C

When the velocity of conductor becomes double, area intercepted becomes twice. Therfore induced current becomes twice
