• Linear actuators

• Microphone assemblies

• Servo motors

• DC motors (automotive starters)

• Computer rigid disc drives, printers and speakers

Notes

Permanent Neodymium magnets are extremely strong for their size. To prevent unwanted oxidation this permanent neodymium magnets is finished with nickel coating. They are highly resistant to demagnetization, have high magnetic energy for size and work well in ambient temperature.

Permanent neodymium is very brittle and very strong magnetically. It is crucial to handle these magnets with extreme care to avoid personal injury and damage to the magnets.

Magnets can chip if allowed to "jump at" an attracting object. Permanent neodymium does not lend itself to conventional machining methods. It can, however, be abrasively ground, but only with the use of liberal amounts of coolant. The coolant minimizes heat fracturing and the risk of fires caused by oxidized grinding dust.
