Two identical circular loops of metal wire are lying on a table without touching each other. Loop-A carries a current which increases with time. In response, the loop-B

A

(a) remains stationary

B

(b) is attracted by the loop `A` s

C

(c ) is repelled by the loop `A`

D

(d) rotates about its `CM` with `CM` fixed

Text Solution

Verified by Experts

The correct Answer is:
C
When the current in loop `A` increasing, the magnetic lines of force in loop `B` loop `A` is near loop `B`. This induces an emf in `B` is such a direction that current flows in opposite direction in `B` (as compared to `A` in the nearer parts). Since current are in opposite directions, loop `B` is repelled by loop `A`.
