If a magnetic material is having magnetic susceptibility `(chi)=-1` then the relative magnetic permeability `(mu_(r))` and type of mangnetic material is

Options

A. 0, diamagnetic
B. 2,ferromagnetic
C. 1,paramagnetic
D. `-1,"diamagnetic"`

Answer

A

Explanation

`Here, chi=-1`
`then, mu_(r)=1+chi Rightarrow mu_(r)=1+(-1)=1-1=0`
Since magnetic susceptibility of given material is less than one. Hence the give magnetic material isa diamagnetic material
