What will be the change in the length of each small bar magnet when a bigger bar magnet is cut into 4 equal parts parallel to the equatorial line ?

A

One-fourth of the initial length

B

Half of the initial length

C

No change in its length

D

One- fourth of the initial length.

Text Solution

Verified by Experts

If the bar magnet is cut into four equal parts perpendicular to the axial line, the length of each small magnet becomes `1//4th` of the initial length.
Hence, the correct option is (a).
