A bar magnet of pole strength $10 \mathrm{Am}$ is cut into two equal parts breadth wise. The pole strength of each magnet is
1 $5 \mathrm{~A} \mathrm{~m}$
2 $10 \mathrm{~A} \mathrm{~m}$
3 $15 \mathrm{~A} \mathrm{~m}$
4 $20 \mathrm{~A} \mathrm{~m}$
Explanation:
A When magnet is cut into two equal parts then the pole strength of each magnet will be halved. The new pole strength is $\mathrm{m}=\frac{10}{2}=5 \mathrm{Am}$ The pole strength of each magnet is $5 \mathrm{Am}$
