If a magnet of pole strenth m is divided into four parts such that the length and width of each part is half that of initial one, then the pole strength of each part will be

A

m

B

`m/2`

C

`m/4`

D

`m/8`

Text Solution

Verified by Experts

The correct Answer is:
B

The bar magnet is cut into four parts as shown in the figure. The pole strength is affected when it is cut parallel to its axis. It is not affected when it is cut parallel to its equator.
`:.` Pole strength of each part will be `m/2`.
