Rare earth permanent magnet applications and the difference
So that the original is not significant magnetic objects to get magnetic in a magnetic field is called " magnetized ." Most easily magnetized ferromagnetic material such as soft iron , silicon and the like. Since the current can cause a strong magnetic field , and easy to control, the constant current generated by a magnetic field so that the magnetization of a ferromagnetic substance called permanent magnets made .
Of natural and man-made magnet magnet magnet . Artificial magnet is divided into two, one is a permanent magnet , the other one is an electromagnet. The difference is that the permanent magnet is made of magnetic material ( such as magnetic alloys, ceramic magnets, etc. ) made while the electromagnet is wound on the outside of the core coil generates a magnetic pass into direct current , the magnetic power immediately after the disappearance . The commonly used permanent magnets. Applications , the permanent magnet magnetic CS operating in the depth of the magnetic saturation magnetization loop and a second quadrant demagnetization section. Permanent magnets should have as high a coercive force Hc, the remanence Br and maximum energy product (BH) m, the maximum magnetic energy storage to ensure stability and magnetic properties.
Made by the permanent magnet separator called permanent magnetic separator , is black concentrator commonly used sorting equipment, and electromagnets are used in low-field electromagnetic devices, such as magnetic screen , pulsating electromagnetic selection
Permanent magnets are widely used in various fields of dry bags, electronics, electrical, mechanical , transportation, medical and household items , etc. . As a speaker , telephone receiver permanent magnet ; magnetic lines of meter magnetic system ; generator , permanent magnet motor pole ; machinery used in manufacturing permanent magnet devices ( such as a permanent magnet sucker surface grinder , etc. ) and suspension system, magnetic bearings ; magnetic separation systems, magnetic separation , magnetic water purification systems , magnetron, proton accelerator magnetic system.
