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 the repulsion between A and B if I is increased

B

There will be the attraction between A and B if I is increased

C

There will be neither attraction nor repulsion when I is changed

D

Attraction or repulsion between A and B depends on the direction of current. If does not depend whether the current is increased or decreased
