Relative permeability of iron is 4000. ...

Relative permeability of iron is 4000. What is its magnetic susceptibility ?

A

`4001`

B

`3999`

C

`4000xx10^(-2)`

D

`4000 xx 10^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
We know that
`chi_(m)=mu_(r)=-1 implies chi_(m)=4000-1=3999`
