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 or decreased.
