Koenigsberger ratio

The Koenigsberger ratio is the proportion of remanent magnetization relative to induced magnetization in natural rocks.^[1] It was first described by Template:Interlanguage link.^[2] It is a dimensionless parameter often used in geophysical exploration to describe the magnetic characteristics of a geological body for help in interpreting magnetic anomaly patterns.

$Q = \frac{M_{r e m}}{M_{i n d}} = \frac{M_{r e m}}{χ H}$ ^[1]

Definition
Template:Mvar	Koenigsberger ratio
$M_{r e m}$	remanent magnetization
$M_{i n d}$	induced magnetization
Template:Mvar	the magnetic susceptibility; the influence of an applied magnetic field on a material
Template:Mvar	the macroscopic magnetic field

The total magnetization of a rock is the sum of its natural remanent magnetization and the magnetization induced by the ambient geomagnetic field. Thus, a Koenigsberger ratio, Q, greater than 1 indicates that the remanence properties contribute the majority of the total magnetization of the rock.^[3]
