A circular loop is kept in that vertical plane which contains the north- south direction. It carries a current that is towards north at the topmost point. Let A be a point on the 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` & towards west at `B`

B

is towards west at `A` & towards east at `B`

C

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

D

is towards west at both `A` and `B`

Text Solution

Verified by Experts

The correct Answer is:
D
Using right hand rule the direction of magnetic field clearly towards west at `A` and `B`
