On the Positions of the Equivalent Poles in a Magnetized Bar Tested by the Magnetometer Method. II : Tungsten Magnet Steel and K. S. Magnet Steel

The distribution of free magnetism in the bars of tungsten magnet steel and K. S. magnet steel in various states of magnetization was measured by drawing out a search coil along the axis of the specimen. Further, the positions of the equivalent poles under the conditions of the axes of the two magnetizing coils in the magnetometer method being in series and parallel with each other were calculated by means of the equations deduced previously by the present authors and G. Otomo. It was found that the positions of the equivalent poles of specimens are remarkably influenced by the sort of material besides the relative position of the magnetized specimen and the magnetometer, the distance between them and the states of magnetization of specimens
