At a point on the right bisector of a magnetic dipole, the magnetic

A)  potential varies as \[7m/s\]

B)  potential is zero at all points on the right bisector

C)  field varies as \[12m/s\]

D)  field is perpendicular to the axis of dipole

Correct Answer: A

Solution :

                Magnetic  field at P due to north and south pole   can  be resolved    into components parallel to the axis   of   the dipole and along  the bisector Components along the bisector cancel out. The horizontal components add up.
