When one magnet is kept in 0.8 T magnetic field, magnetic force on each its two poles is 0.08 N. Then pole strength of each pole would be ......

A

`10` Am

B

`0.1` Am

C

`0.1 Am^2`

D

`10 Am^2`

Text Solution

Verified by Experts

The correct Answer is:
B

`F= q_(m) B therefore q_(m) = (F)/( B) = (0.08)/(0.8) = 0.1` Am
