MCQ

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 $B$
✓
is towards east at both $A$ and $B$
D
is towards west at both $A$ and $B$

✓

Answer

Correct option: C.

is towards east at both $A$ and $B$
