An electron moves on a straight line path XY as shown. The abcd is a coil adjacent to the path of electron. What will be the direction of current, if any, induced in the coil ?

A

No current induced

B

In abcd direction

C

In adcb direction

D

The current will reverse its direction as the electron goes past the coil

Text Solution

Verified by Experts

The correct Answer is:
D

First current develops in direction of abcd but when electron moves away, then magnetic field inside loop decreases & current changes its direction.
