Two circular coils `A` and `B` are facing each other as shown in figure. The current `i` through `A` can be altered

A

There will be repulsion between `A` and `B` if `i` is increased

B

There will be attraction between `A` and `B` if `i` is increased

C

There will be neither attraction nor repulsion when `i` is changed

D

Attraction or replusion between `A` and `B` dependes on the direction of current. If does not depend wheter the current is increase or decreased

Text Solution

Verified by Experts

The correct Answer is:
A
with rise in current in coil `A` flux through `B` increases. According to Lenz's law repulsion occures between `A` and `B`.
