摘要
根据磁偶极子链的物理特性及带圆形通孔和矩形通孔销钉的几何特点,推证出纵向磁化时带圆形和矩形通孔销钉圆柱面上的磁痕形状,与试验所得的奇特磁痕完全一致。
On the basis of the physical characteristic of the magnetic dipole chains and the geometrical feature of a pin with a circular through hole and a pin with a rectangular through hole, the shape of magnetic particle pattern over the cylindrical surface of the pin with a circular or a rectangular through hole was deduced, and it all coincided with the strange magnetic particle pattern obtained by the magnetic particle testing experiment.
