Summary
When an alternating-current transport current and/or an alternating-current magnetic field are applied to multiply twisted superconducting cables, a magnetic field along strands composed of homogeneous and spatially periodic components is induced in addition to the field perpendicular to the strands. The time variation of this longitudinal field along the strands also brings about hysteresis and coupling-current losses. Theoretical expressions for the additional losses are derived both in the self-field configuration of the cable and in the external transverse field configuration. Practical consequences are shown.
