Abstract
The influence of oscillating magnetic fields of low frequency on the DC transport current in a twisted multifilamentary conductor has been studied by observing the terminal voltage of the conductor. An analysis of the voltage versus oscillating field characteristics, combined with theoretical considerations, shows that the current distribution among filaments becomes uniform due to the oscillation of the field and an effective resistance appears in the transport current when the amplitude of the oscillating field exceeds certain threshold value. The dependence of the effective resistance on the characteristic parameters of both the oscillating field and the filamented conductor is clarified.
