Magnets are an important part of our daily lives, serving as essential components in everything from electric motors, loudspeakers, computers, compact disc players, microwave ovens and the family car, to instrumentation, production equipment, and research. Their contribution is often overlooked because they are built into devices and are usually out of sight.
Magnets function as transducers, transforming energy from one form to another, without any permanent loss of their own energy.
The most powerful permanent magnet, offers a great return for cost & performance, have the highest field/surface strength(Br), high coercivity(Hc), can be easily formed into various shapes and sizes. Be reactive with moisture and oxygen,usualy supplied by plating (Nickel, Zinc, Passivatation, Epoxy coating, etc.).
NdfeB Neodymium rare earth permanent magnets are widely use in many area,Such as Motors, Sensor, Speaker, Rotors, Alarm, Microphone, Wind turbines/Wind generators, Magnetic Hooks, Magnetic Holder, Filters automoblies and so on.
