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.
