Maradékmagnetizáció
Maradékmagnetizáció, often translated as remanence or residual magnetism, refers to the magnetic field that remains in a ferromagnetic material after an external magnetic field has been removed. When a ferromagnetic material is exposed to a magnetic field, its magnetic domains align themselves with the external field. Upon removal of this field, not all of these domains return to their original random orientation. Instead, a certain degree of alignment persists, creating a net magnetic moment.
This residual magnetism is a crucial property in many applications. For instance, it is fundamental to the
The amount of maradékmagnetizáció retained by a material depends on its magnetic properties, particularly its coercivity.
