摘要
为进一步研究开发新型高梯度磁选设备,对圆柱形导磁介质在外磁场中因磁化而在端面产生的二次磁场特性进行了研究。推导出圆柱形导磁介质端面产生的二次磁场分布公式;分析了影响该二次磁场力的各因素,得出了圆柱形导磁介质端面半径R与作用距离r的特征关系,以及最大磁场力随作用距离的变化关系式;指出圆柱形导磁介质的最大磁场力力程仅取决于圆柱形导磁介质的磁化状态。
The remagnetic field on the end of cylindrical ferromagnetic material caused by the background magnetic field was studied in this paperThe expression for the remagnetic field was derivedThrough analyzing the factors affecting the remagnetic field force,the expression for a function of the maximal magneticfield force to the distance was established and the characteristic relation between the end radius of the cylindrical ferromagnetic material and action distance was foundIt was pointed out that the range of the maximal magneticfield force is only dependent on the magnetization characteristic of the cylindrical ferromagnetic material
