Macroscopic properties of magnetics

The magnetization of a substance is quantitatively characterized by magnetization 3, which is numerically equal to the magnetic moment of a volume unit 

Alongside with magnetization of a unit volume, a specific and mole magnetization are considered as well. The specific magnetization (magnetization of a mass unit) is equal to  

Alongside with magnetic susceptibility x of the unit volume a specific magnetic susceptibility Xsp is often used in practice Xsp=(3sp/ ) the relation being exist Xsp ( /p)X- The same is for molar magnetic susceptibility Xm which is equal to
