A circular loop is kept in that vertical plane which contains the north-south direction. It carries a current that is towards south at the topmost point. Let \( A \) be a point on axis of the circle to the east of it and \( B \) a point on this axis to the west of it. The magnetic field due to the loop
(A) is towards east at \( A \) and towards west at \( B \)
(B) is towards west at \( A \) and towards east at \( B \)
(C) is towards east at both \( A \) and \( B \)
(D) is towards west at both \( A \) and \( B \)
