A circular loop placed in a plane prependicular to the plane of paper carries a current when the key is On. The current as seen from points A and B (in the plane of paper and on the axis of the coil) is anti -clockwise and clockwise respectively. The magnetic field lines point form B to A. The N-pole of the result magnet is on the face close to

A

A

B

B

C

A, if the current is small, and B if the current is large.

D

A, if the current is small, and A if the current is large.

Text Solution

Verified by Experts

The correct Answer is:
A
Magnetic field lines are in the direction from South Pole to North Pole . Point A is showing North Pole because field lines are pointing from B to A.
