The correct M-H curve for a paramagnetic material at a constant temperature (T) is represented by

Options

A.
B.
C.
D.

Answer

A

Explanation

Since instesty of magnestisation (M) of a paramagentic material is given by
`M=C(B)/(T)=Cmu_(0) (H)/(T)as (Cmu_(0))/(T)"is constant"`
`"Then", M alphaH`
Hence, the M-H curve will be a straight line with the slope, `Cmu_(0)(1)/(T)`
