The term emu is short for 'electromagnetic unit' and is not a unit in the conventional sense. It is sometimes used as a magnetic moment (1 emu = 1 erg G?1) and
This magnetisation is a measure of the magnetic moment per unit volume of material but can also be expressed per unit mass
This magnetization is opposite to the external magnetic field. magnetization can form permanent magnets. ... The unit of magnetization M is Am?1.

MagnetizationMis a normalized moment (Am2) We will use the symbol Mfor vol-ume normalization (units of Am?1) and ? for mass normalization (units of Am2kg?1) Volume-normalized magnetization therefore has the same units as H implying thatthere is a current somewhere even in permanent magnets

The quantit y M is called the magnetization of the material. In SI units it is expressed in A m-1. We see that there are two components t o B. T here is the ? o H = ? o n I, wh ich is the externally imposed field, and the componen t ? o M, o riginating as a result of something that has happened within the material.
Net magnetization results from the response of a material to an external magnetic field. Paramagnetic materials have a weak induced magnetization in a magnetic field, which disappears when the magnetic field is removed.
The SI unit of magnetic induction is T (tesla). Each magnetic moment of a molecular magnet, including atoms or ions, is accounted for as a whole by vector summation. This physical parameter needs a counting base, such as unit volume, unit weight, or, more generally, unit quantity of substance.
