A bar magnet is placed with its North pole pointing North. Neutral point is at a distance `'d'` from the center of magnet. The net magnetic induction at the same distance on the axial line of the magnet is

A

`2B_(H)`

B

`3B_(H)`

C

`B_(H)`

D

`7B_(H)`

Text Solution

Verified by Experts

The correct Answer is:
B
`B_(e)=B_(H)` and `B=B_(a)+B_(H)=2B_(e)+B_(H)=2B_(H)+B_(H)=3B_(H)`
