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 find the magnetic moment of a dipole given the magnetic scalar potential at a point on its axis, we can follow these steps:

### Step 1: Understand the formula for magnetic scalar potential
The magnetic scalar potential \( V \) due to a magnetic dipole is given by the formula:
\[ V = \frac{\mu_0}{4\pi} \cdot \frac{m \cos \theta}{r^2} \]
where:
