1. Application and purpose of ndfeb magnet

At present, the main application areas of ndfeb magnet are: permanent magnet motors, generators, nuclear magnetic resonance imaging, magnetic separators, audio speakers, magnetic levitation systems, magnetic transmission, magnetic lifting, instrumentation, liquid magnetization, special-shaped magnet magnetic therapy equipment, etc. , Has become an indispensable functional material for automobile manufacturing, general machinery, petrochemical industry, electronic information industry and cutting-edge technology.
2. Comparison between ndfeb magnet and other permanent magnet materials
The ndfeb magnet is currently the world’s strongest permanent magnet material. The special-shaped ndfeb magnet has a magnetic energy product ten times higher than that of widely used ferrites and about twice as high as the first and second generation rare earth magnets. It is known as "permanent The King of Magnetism". Using it instead of other permanent magnetic materials can double the volume and weight of the device. Due to the rich resources of neodymium, compared with samarium-cobalt permanent magnets, the special-shaped ndfeb magnet replaces the expensive cobalt with iron, which makes the product high in quality and low in price, which has been widely used.
The ndfeb magnet material is a permanent magnet material based on the intermetallic compound Nd2Fe14B. Neodymium iron boron has extremely high magnetic energy product and coercivity, and can suck up heavy objects 640 times its own weight. The advantages of high energy density make neodymium iron boron permanent magnet materials widely used in modern industry and electronic technology, making it possible to miniaturize, lighten, and thin equipment such as instrumentation, electroacoustic motors, and magnetic separation and magnetization.
