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
