A magnet of magnetic moment M amd pole strenth m is divided in two equal parts, then magnetic moment of each part will be

Text Solution

Verified by Experts

The correct Answer is:
B
If magnet is cut along the axis of magnet of legnth l, then new pole strength becomes half `i.e, m'=(m)/(2)` and new length remains same I.e., l'=l
New magnetic moment
`M'=(m)/(2)xxl=(ml)/(2)=(M)/(2)`
