Definitions for "Remanence"
Property of, particularly volcanic, rocks to be permanently magnetized in the direction of the Earth's magnetic field that existed at the time that the rock cooled below a certain temperature, which we call the Curie temperature (~-400-500 o). The direction of magnetization of these rocks does not change when they are transported to another location on earth.
The magnetic induction that remains in a magnetic circuit after the removal of an applied magnetizing force.
Amount a material remains magnetized after the magnetizing force has been removed.
