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