Magnetic induction at a point due to sho...

Magnetic induction at a point due to short magnetic dipole is`B_(1)`.The dipole is then cut into two equal parts.Magnetic induction at the same point due to either part is

A

`(B_(1))/(4)`

B

`(B_(1))/(2)`

C

`B_(1)`

D

`2B_(1)`

Text Solution

Verified by Experts

The correct Answer is:
B
If the bar magnet is cut into two equal parts then each part has as magnetic moment equa, to M/2 therefore,magnetic induction at that point is also `B_(1)//2`.
