A circular loop placed in uniform B is transformed into elliptical loop as shown in fig. Direction of induced current if any during transformation will be:

A

Clockwise

B

Anticlockwise

C

No induced current

D

First clockwise, then anticlockwise

Text Solution

Verified by Experts

The correct Answer is:
A
`varphi=Bararr` for a given length of wire maximum area is enclosed by circle.
So A decreses, thus B should be increased. So CW current will induce in loop.
