the ratio of the magnetization to the external magnetic field that induces it Magnifying glass – a single converging lens that, when held near the eye, gives an image whose size on the retina is larger than that observed by the unaided eye
A measure of the degree to which a body is magnetized. In SI units this is related to relative magnetic permeability by k=µr - 1, and is a dimensionless unit. For most geological material, susceptibility is influenced primarily by the percentage of magnetite. It is most often quoted in units of 10-6. In HEM data this is most often apparent as a negative in-phase component over high susceptibility, high resistivity geology such as diabase dikes.
a physical property that in sediments is determined by their mineral composition, and in some cases, by particle size. When a sample is placed in a magnetic field, it becomes magnetic. The ratio of induced magnetization to magnetic field strength is the susceptibility
