Question

A bar magnet of pole strength $10Am$ is cut into two equal parts breadthwise. The pole strength of each magnet is :

Answer 1

If a bar magnet is cut into two equal parts, then the pole strength of each magnet will be halved.

The new pole strength is given as,

$m=\frac{10}{2}$

$m=5A-m$

Thus, the pole strength of each magnet is $5A-m$.
