A paramagnetic substance of susceptibility `3xx10^(-4)` is placed in magnetic field of '4xx10^-4' magnetization in the units of `Am^(-1)` is

A

`1.33xx10^(8)`

B

`0.75 xx10^(8)`

C

`12xx10^(-8)`

D

`14xx10^(-8)`

Text Solution

Verified by Experts

The correct Answer is:
C
Intensity of magnetization
=susceptibility x x field B
`rarrI=Bx=(4xx10^(-4))xx(3xx10^(-4))=12xx10^(-8) am^(-1)`
