【摘要】 介绍了置于无限大均匀外磁场里的长轴与外磁场平行的铁磁性椭球体内外磁场和磁力的解析计算方法,讨论了它在磁选研究方面的功用。论述了特殊点的直角坐标与椭球坐标之间的对应关系,这便于用文内公式计算各点上的磁场和磁力,有利于对磁选技术的研究。更多还原

【Abstract】 The method of analytical calculate the magnetic field and the magnetic force inside and outside a ferromagnetic ellipsoidal ball placed in a boundless even external magnetic field,together with its contribution to magnetic separation,is given.In the calculation the long axis of the ellipsoidal ball is parallel to the external magnetic field.The corresponding relation betweent the orthogonal coordinates and the ellipsoidal coordinates of the special points is presented.It is convenient for calculating the magnetic field and the magnetic force at every point with the formulas in this paper and for research on magnetic separation.更多还原
