Magnetic Properties of Ma question bank (Physics)

The ratio of magnetic fields due to a bar magnet at the two axial points P₁ and P₂ which are separated from each other by $10 \mathrm{cm}$ is $25:2$. P₁ Point is situated at$10 \mathrm{cm}$ from the centre of the magnet. (Points P₁ and P₂ are on the same side of magnet and distance of P₁ and P₂ from the centre of magnet is much greater than the distance of two ends of the magnet from the centre). Magnetic length of the bar magnet is
