Which magnetic have negative susceptibility?

A

paramagnetic material onty

B

ferromagnetic material only

C

paramagnetic and ferromagnetic materials

D

diamagnetic materials only

Text Solution

Verified by Experts

The correct Answer is:
D
As we know the relation between the magnetic permeability and susceptibility of material is `mu_(r)=1+chi_(m) ..........(i)`
For diamagnetic substances, `mu_(r)lt1`
So, accordingly to Eq. (i), the magnetic susceptiblity `(chi_(m)` of diamagnetic substance will ne negative
Wile in case of para and ferromagnetic substances subsceptiblity is positive.
