Also found in: Thesaurus, Encyclopedia.
Of or characteristic of substances such as iron, nickel, or cobalt and various alloys that exhibit extremely high magnetic permeability, a characteristic saturation point, and magnetic hysteresis.
fer′ro·mag′ne·tism (-măg′nĭ-tĭz′əm) n.
(Minerals) the phenomenon exhibited by substances, such as iron, that have relative permeabilities much greater than unity and increasing magnetization with applied magnetizing field. Certain of these substances retain their magnetization in the absence of the applied field. The effect is caused by the alignment of electron spin in regions called domains. Compare diamagnetism, paramagnetism See also magnet, Curie-Weiss law
The magnetic property of cobalt, iron, nickel, and some alloys.
