Neodymium iron boron magnetic materials have high energy product, high coercivity, and good stability, making them the most widely used, cost-effective, and comprehensive magnetic materials, stimulating a significant increase in demand for rare earth resources. The performance advantages of neodymium iron boron magnetic materials mainly lie in the following aspects. Firstly, it has strong magnetism. Neodymium iron boron permanent magnet is currently the second most magnetic permanent magnet after absolute zero degree holmium magnet, with a magnetic energy product greater than samarium cobalt magnet. Secondly, it is small in size and lightweight. Due to its high magnetic strength, in the application process, only a small amount of neodymium iron boron magnetic material is needed to generate the same magnetic field as a large number of other materials, which can significantly reduce the product volume and reduce product quality. Thirdly, it has strong stability and high usage efficiency. Neodymium iron boron magnetic materials have good anti magnetic loss performance and can work stably in high temperature environments.
