The magnetic moment of a magnet of dimensions `4 cm xx 2 cm 1.25 cm ` is `3 Am m^(2)` what is the intensity of magnetisation ?

A

`3xx10^(5)` Amp/m

B

`2xx10^(5)` Amp/m

C

`10^(5)` Amp/m

D

`4xx10^(5)` Amp/m

Text Solution

Verified by Experts

The correct Answer is:
A
`I=(M)/(V)=(3)/(4xx2xx1.25xx10^(-6))`
`=3xx10^(5) "Amp" m^(2)//m^((3)=3xx10^(5)` Amp/m
