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

Answer

B

Explanation

Here,
`M_(2)` = magnetization of a paramagnetic sample
B= external magnetic firld
T= absolute temperature
C = Curie constant
Curie's law in magnetism states in paramagnetic material, the states that in paramagnetic material, the material's magnetization is directly proportional to the applied field, but when temperature increases the relation is reversed, i.e, the magnetization becomes inversely proportional to the temperature. Mathematically, it is written as
`M_(2)=(CxxB)/(T)rArrC=(M_(2)*T)/(B)`
