摘　　要：本文从磁荷间的相互作用力和相互作用能出发,论证了长方体磁介质纵向磁化后磁荷将均匀地分布在所有各条棱线上,从而阐明了长方体纵向磁化后侧棱上出现非相关(杂乱)显示的原因。It is demonstrated by both cases of interaction force and interaction energy between magnetic charges that magnetic charges uniformly distribute along all the edges of a cuboid after longitudinal magnetization of the magnetic medium, thereby it is explained theoretically why the non-relevant (stray) indications will occur after longitudinal magnetization of a cuboid along its lateral edges.
