摘要
针对矩形永磁体的静磁分布问题,测量了矩形磁体空间的磁场分布,分析了三维磁场分布形态,得到了单磁体磁化方向分量以及磁化方向的垂直方向分量沿不同坐标轴的量值分布.并且得出了相斥双磁体磁场及相吸双磁体磁场各分量的空间分布形态及分布特征,验证了磁场空间矢量叠加的性质.
With increasing applications of permanent magnetic materials in magnetic levitation system, com- prehensive understanding of the field around the permanent magnetic materials becomes more and more important. For the stationary magnetic field of rectangular permanent magnet, the paper gave the spacial distributions of it by experimental method and analyzed the distribution characteristics in three dimensions. The numeric distributions of ponderances in magnetization magnet along different coordination were given. direction and in vertical direction of magnetization of single Furthermore, the paper worked out spatial distribution statures and characteristics of all the ponderanees of repultive magnets and attractive magnets, and testified the overlapping attribute of magnetic vactor in space.
