Two circular coils A and B are facing each other as shown in the diagram. The current i through A can be altered, then

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.
