K. Komatsu et al., DYNAMIC MAGNETIZATION PROCESS IN FECOSIB AMORPHOUS WIRE UNDER TRIGONAL MAGNETIC-FIELD, IEEE transactions on magnetics, 32(5), 1996, pp. 4992-4994
A magnetization process of FeCoSiB amorphous wire under the ac circumf
erential magnetic field with a triangular waveform is investigated. We
obtained the locus chart of the magnetization vector under circular m
agnetic field, h(theta). By increasing the time differential component
of h(theta), dh(theta)/dt, the hysteresis becomes noticeable graduall
y. It is believed that an eddy current damping is responsible for this
phenomenon.
