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/4

B

m/2

C

m/8

D

4m

Text Solution

Verified by Experts

The correct Answer is:
B

The situation is summarised in figure , we see that magnetic pole strength of each part becomes half i.e., m/2.
