Q. A bar magnet having centre $O$ has a length of $4 cm$ : Point $P_{1}$ is in the broad side-on and $P_{2}$ is in the end side-on position with $O P_{1}=O P_{2}=10$ metres. The ratio of magnetic intensities $H_{1}$ and $H_{2}$, respectively, at $P_{1}$ and $P_{2}$ is

Magnetism and Matter

Solution:

Magnetic intensity in end side on position is twice that in the broad side on position.
