摘    要：通过计算磁场里的铁磁性椭球内部及外部的磁场,说明了随着椭球材料磁导率的减小,椭球的聚磁能力下降,同时为提高磁场吸引矿粒的力所需增加的电耗更多。

Abstract: By means of calculating the magnetic field inside and outside a ferromagnetic ellipsoid located in a magnetic field,it is illustrated that with the reduction of magnetic conductivity in ellipsoid the capacity to gather magnetic flux comes down,and at the same time the electric consumption is more greatly increased for raising magnetic attractive force to mineral particle.
