The ratio of the magnetic fields due to ...

The ratio of the magnetic fields due to small bar magnet in end position an broad side on position is (at equal distance from the magnet)

A

`1//4`

B

`1//2`

C

1

D

2

Text Solution

Verified by Experts

The correct Answer is:
d
(d) End on position corresponds to axial line and Broadside on position corresponds to equatorial line. Therefore,
`B_(1)//B_(2)=2`.
