A loop and an infinite wire are placed side by side as shown in the figure. If the current I in the wire is increased then the induced current in the loop is

A

clockwise

B

anticlockwise

C

zero

D

cannot determine

Text Solution

Verified by Experts

The correct Answer is:
A
When I increases, the flux through loop increases outward. From Lenz. law, induced current opposes this change in flux and therefore clockwise current is induced in the loop.
