Permanent Magnetic Materials - Magnetic Products Magnets ...

7 行  Magnet materials are difficult to machine, except Flexible and Bonded, because they are brittle and the dust sticks to everything. To have magnets cut is expensive ($150 minimum set up). To make a mold is expensive ($3500 min.). Designing your application around an industry standard magnet can SAVE YOU BIG MONEY.

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.
