The current flows from A to B in a straight wire as shown in figure and it is decreasing with time. The induced current in loop placed near to it ____

A

In clockwise direction

B

In anticlockwise direction

C

Will not be produced

D

Nothing can be said

Text Solution

Verified by Experts

The correct Answer is:
B
The magnetic flux associated with loop is perpendicularly upward to the plane of loop and also according to the Lenz.s law due to the decreasing current from wire AB, induced current in the loop in such a direction that magnetic field produced is perpendicularly upward to the plane of the loop. The end of this loop act as N (North pole) and according to Lenz.s law the direction of induced current will be in anti-clockwise.
