Diamagnetic is a term that refers to the property of materials that do not maintain permanent magnetization when exposed to an external magnetic field. Synonyms for diamagnetic include non-magnetic, unmagnetized, non-attractive, and non-ferromagnetic. These words are used to describe materials that are not attracted to magnets, do not produce magnetic fields, and do not retain magnetization. Diamagnetic materials have a negative magnetic susceptibility and are repelled by magnetic fields. Synonyms for diamagnetic are often used in scientific research, in particular within the fields of physics and chemistry, when referring to materials that are not magnetically active, which can greatly affect the chemical and physical properties of these materials.
