How many applications of Ndfeb permanent Magnets do you know

What are the main applications of NdFeB permanent magnet materials? In the more than one hundred years since the invention of the first man-made tungsten steel permanent magnet, new permanent magnets with better comprehensive magnetic properties have been introduced. Especially after entering the 1930s, new permanent magnets with better comprehensive performance will be successfully developed and put on the market almost every 3 to 5 years. The reason why permanent magnets have developed so fast is that permanent magnets have the advantages that do not consume their own magnetic energy for external work, and have no noise, no pollution, high efficiency, energy saving, long life, high reliability, easy use, no need for separate management, etc. Therefore, permanent magnets are used in generators, motors, meters, instruments, sensors, medical equipment, mineral processing, automatic control, laser accelerators, electronics, home appliances, aerospace, aviation, ships, electric vehicles, electric bicycles, rob
