A short bar magnet is placed along positive X-axis with its centre at origin. Calculate the magnitude of magnetic field strength at point (0,5 cm), if the magnetic moment of the bar magnet is `0.5 Am^2`

Explanation

To calculate the magnitude of the magnetic field strength at the point (0, 5 cm) due to a short bar magnet with a magnetic moment of \(0.5 \, \text{Am}^2\), we can use the formula for the magnetic field \(B\) along the axial line of a bar magnet, which is given by:

\[ B = \frac{\mu_0}{4\pi} \cdot \frac{2M}{r^3} \]

Where:
- \(B\) is the magnetic field strength,
