On the Positions of the Equivalent Poles on a Magnetized Bar Tested by the Magnetometer Method. III : Electrolytic Iron and Mo-Cr Permalloy

The distribution of free magnetism on the bars of electrolytic iron and Mo-Cr permalloy in various states of magnetization has been measured by shifting a search coil along the axis of the specimens, and using the data obtained here, the positions of equivalent poles, when the axes of the two magnetizing coils in the magnetometer method are on the same line or in parallel, have been calculated by means of the equations deduced previously by the present investigators and Mr. G. Otomo. And it has been again clarified that the positions of equivalent poles of specimens are remarkably influenced by the relative position of the magnetized specimen and the magnetometer, the distance between them, the states of magnetization of specimens, and the sort of materials
