Definition
Ferromagnetism is a property of certain materials where they can become strongly magnetized in the presence of an external magnetic field. This occurs due to the alignment of atomic magnetic moments within the material.
Related terms
Paramagnetism: Paramagnetic materials are weakly attracted to an external magnetic field due to unpaired electrons.
Diamagnetism: Diamagnetic materials are weakly repelled by an external magnetic field due to paired electrons.
Curie Temperature: The Curie temperature is the temperature at which a ferromagnetic material loses its magnetization and becomes paramagnetic.
