(d)Magnetic potential at a distance d from the bar magnet on it's axial line is given by
$V = \frac{{{\mu _0}}}{{4\pi }}.\frac{M}{{{d^2}}}$ $&rArr;$ $V \propto M$ $&rArr;$ $\frac{{{V_1}}}{{{V_2}}} = \frac{{{M_1}}}{{{M_2}}}$
$&rArr;$ $\frac{V}{{{V_2}}} = \frac{M}{{M/4}}$ $&rArr;$ ${V_2} = \frac{V}{4}$

The magnetic potential at a point on the axial line of a bar magnet of dipole moment $M$ is $V$. What is the magnetic potential due to a bar magnet of dipole moment $\frac{M}{4}$ at the same point
