A bar magnet of magnetic dipole moment 8 `Am^(2)` has poles separated by `0.4` m . Find the pole strength of bar magnet .

Explanation

To find the pole strength of the bar magnet, we can use the relationship between the magnetic dipole moment (M), the pole strength (m), and the separation between the poles (2L). The formula is given by:

\[ M = m \times 2L \]

Where:
- \( M \) is the magnetic dipole moment,
- \( m \) is the pole strength,
- \( 2L \) is the distance between the poles.
