钕铁硼磁性材料,作为稀土永磁材料发展的最新成果,由于其优异的磁性能而被称为“磁王”.钕铁硼和我们平时见到的磁铁所不同的是一种具有极高的磁能积和矫顽力,同时高能量密度的优点使钕铁硼永磁材料在现代工业和电子技术中获得了广泛应用,从而使仪器、仪表、电声电机、磁选磁化等设备的小型化、轻量化、薄型化成为可能.去年我校购进一些小型强磁铁被应用到传统的演示实验中,对经典的演示实验进行了改进,取得出人意料的效 NdFeB magnetic materials, as the latest achievements in the development of rare earth permanent magnet materials, due to its excellent magnetic properties and is known as “magnetic king.” NdFeB and we usually see the magnet is a kind of very High magnetic energy product and coercive force, meanwhile the advantages of high energy density make NdFeB permanent magnet material widely used in modern industry and electronic technology, so that the equipment, instrument, electro-acoustic motor, magnetic separation magnetization and other equipment Miniaturization, lightweight, thin as possible last year, I purchased some small magnets to be used in traditional demonstration experiments, the classic demonstration experiments have been improved and achieved unexpected results
