The magnetization process of FeCoSiB amorphous wire under an ac circumferential magnetic field with a triangular waveform is investigated. We obtain the locus chart of the magnetization vector under a circular magnetic field, h/sub e/. By increasing the time differential component of h/sub e/, dh/sub e//dt, the hysteresis becomes noticeable gradually. It is believed that an eddy current damping is responsible for this phenomenon.
