On the sintered 18 percentt chromium 2 percent molybdenum iron magnetic alloys containing four sorts of silicon composition, the change in the value of coercive force which arises with the measuring speed to make a round of the hysteresis loop was measured and discussed. Similar changes have been observed in the apparent coercive force with the thickness of specimen for sintered alloy too. And the phenomenon was influenced by the change of resistivity owing to the silicon composition and the sintering temperature. These apparent coercive forces were constricted to the sole value when the inverse of measuring speed become to zero. This value may he the essential coercive force. But precise relationship of the change in apparent coercive force and resistivity could not make clear. The phenomenon is originated in the delay of magnetization and clearly depended on the ratio of μ∝/ρ at the nearest point of apparent coercive force.
