- In geomagnetic field: Crustal magnetization
Induced magnetization occurs when the elementary magnetic dipoles of crustal materials are aligned by Earth’s main field, just as a compass needle is aligned. If a material of particularly high susceptibility to magnetization is concentrated, as in a mineral deposit, it also can be approximated…
