Magnetic method can be useful to investigate subsurface geology on the basis of anomalies in the earth's magnetic field resulting from the magnetic properties of the underlying rocks. The strength of the magnetic anomaly depends on the magnetic susceptibility contrast between the source and the surrounding rocks.

The magnetism of a rock is determined by the magnetic properties of electrons outside the atoms. When suspended in air, electrons tend to spin in any direction. Consistent magnetic fields generated by rocks such as lodestones cause elements such as iron to magnetize. Typically, the amount of heat applied to rocks increases their magnetic field.
