we can determine the reversal permeability (Figure 2.5)

(Bozorth 1951, Morrish 2001).

2.2.5 Susceptibility χ

In some applications, especially in physical analysis of

magnetization processes, susceptibility χ is used more

often than permeability as the quantity linking magne-

tization M and the magnetic eld strength H:

M H= χ

(2.22)

There is a simple relationship between permeability

and susceptibility:

μ χ

Measurement of magnetic susceptibility is commonly

used in paleomagnetism to investigate the remanent

magnetization of the rocks (see Section 6.1.3). Magnetic

susceptometry is ...
