Application of Rare Earth Magnets HISTORY

permanent magnet material and the emergence of a long history. China's Warring States period (475 BC to 221 BC), people in the use of natural magnetite ore grinding into the necessary shape to the Guide. The last century, with the rapid development of science and technology, permanent magnet material progress, the new permanent magnet materials to promote the emergence of a permanent magnet device improvements and development. And the demand for high-tech and promoting the emergence of a new permanent magnet materials. "Therefore we can say that the new permanent magnet materials development and application of the high-tech industry in an extremely important part. Rare earth permanent magnet, especially NdFeB emergence of modern high-tech industries will have a tremendous impact.

1. Permanent magnet material on the progress of the impact of permanent magnet devices

permanent magnet material (CARICOM) in a designated room for a constant magnetic field of materials. Permanent magnet can be used alone, but also with other ferromagnetic and non-magnetic materials composed of magnetic iron, then a magnetic device. Permanent magnet materials performance enhancement will enable small size of the device, which makes a variety of modern industries permanent magnet devices small, micro and lightweight as possible. Permanent Magnetic Materials, one of the most important characteristics of energy product (BH) max description of the progress of permanent magnet materials and the impact of the magnetic devices.
¤ö ¤ö the emergence of new materials always have new capabilities, such as rare earth permanent magnet material with other types of permanent magnet material than high coercivity, which features open up a new class of applications and devices.
