Definition - What does Ferromagnetic mean?
Ferromagnetic is a property of some materials, which works on the principle of ferromagnetism, the basic mechanism by which ferromagnetic materials such as ferrous alloys acquire the properties of magnets to form permanent magnets or are attracted toward a magnet. A material is said to be ferromagnetic only if all of its magnetic ions contribute to an increase in the net magnetization of the material.
The ferromagnetism characteristics exhibited by ferromagnetic materials have very important applications in industry and technology.
Corrosionpedia explains Ferromagnetic
Ferromagnetic materials are the basis of many electromechanical and electrical devices such as electric motors, electromagnets, magnetic storage devices, transformers and generators.
Ferromagnetic materials such as iron and other ferrous alloys contain unpaired electrons. Each electron has its own magnetic field that readily aligns itself whenever a magnetic field is encountered from an external magnetic field. This alignment tends to remain even when the external magnetic field is removed, so that the ferromagnetic material subsequently acquires the properties of a magnet. This behavior is known as hysteresis and is the principle of operation of synchronous electric motors and some other electrical devices.
