The magnetic potential at a point on the axial line of a bar magnet of dipole moment

M

V

. What is the magnetic potential due to a bar magnet of dipole moment

\frac{M}{4}

at the same point

View answer and explanation

Correct option: D

\frac{V}{4}

Option D (

\frac{V}{4}

) is correct because the magnetic potential is directly proportional to the magnetic dipole moment.
