A current from A to B is increasing in magnitude. What is the direction of induced current, If any, in the loop as shown in the figure?

A

No current will be induced

B

the current will be clockwise

C

the current will be anticlockwise

D

the current will change direction as the electron passes by

Text Solution

Verified by Experts

The correct Answer is:
D

As the electronic is moving from left to right, the flux linked with the loop (which is into the page) will first increase and then decrease as the electron passes by.So the induced current in the loop will be first anticlokwise and will changedirection as the electron passes by. `A` cylindrical bar magnet is kept along the axis of a circular coil. if the magnet is rotated about its axis, then
