Permanent Magnet Materials and Current Challenges

Magnet: A material that produces a magnetic field. Soft Magnetic Material: A material that in the presence of an externally applied magnetic field exhibits its own magnetism. When the external field is removed it no longer exhibits a magnetic field. Permanent Magnet: A material that, once magnetized, continues to exhibit an external magnetic field in the absence of external stimulus.

Permanent Magnets | Custom Magnets & Magnetic Assemblies

Permanent magnets are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth metals and minerals such as lodestone. Unlike electromagnets, permanent magnets produce a persistent magnetic field without the need for any external source of magnetism or electrical power.
