One magnet is cut perpendicular to its axis and divided into two pieces with the lengths in the ratio 2 : 1. Then ratio of their pole strength is ......

A

`2:1`

B

`1:2`

C

`4:1`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:

D

Because in this case, cross-sectional area remains same and so pole strength remains same.
