The magnetic scalar potential due to a magnetic dipole at a point on its axis situated at a distance of 20cm from its centre is found to be `1.2 xx 10^(-5) T m`. Find the magnetic moment of the dipole.

Explanation

To solve the problem, we need to find the magnetic moment \( M \) of a magnetic dipole given the magnetic scalar potential \( V \) at a point on its axis. The magnetic scalar potential \( V \) at a distance \( r \) from the dipole is given by the formula:

\[ V = \frac{\mu_0}{4\pi} \frac{M \cos \theta}{r^2} \]
