If `M_(z)` = magnetisation of paramagnetic sample B= external magnetic field T= absolute temperature, C= curie constant then according to Curie's law in magnetism, the correct relation is

Options

A. `M_(x) =(T)/(CB)`
B. `M_(z)=(CB)/(T)`
C. `C=(M_(z)B)/(T)`
D. `C=(T^(2))/(M_(z)B)`

Answer

B

Explanation

According to Currie's law,
`cancel lamdaprop 1/T` where `cancel lamda` - susceptibility
`therefoer cancel lamda =C/T` where C - curie's constant
`(M_(z))/(B) =C/Twhere cancel lamda=(M_(z))/(B)`
`therefore M _(z) =(BC)/(T)`
