jäännösmagnetisaatiolla
Jäännösmagnetisaatio refers to the residual magnetism that remains in a ferromagnetic material after the external magnetic field that caused it has been removed. This phenomenon is a key property of magnetic materials and is fundamental to technologies such as magnetic storage and permanent magnets.
When a ferromagnetic material is exposed to a magnetic field, its magnetic domains, which are microscopic regions
Materials with high remanent magnetization and high coercivity are desirable for applications requiring strong and stable
