摘要：

The principle of minimum energy dissipation rate is applied for calculation of steady interstrand eddy currents in flat two-layer superconducting cables subjected to transverse time-dependent magnetic fields which are non-uniform along the cable. The resulting eddy current patterns and corresponding energy losses are found to depend strongly on whether the longitudinal profile of the magnetic field contains a significant harmonic term with a period equal to the cable twist pitch. The limitations imposed by the sample geometry and the ramp rate on the experimental confirmation of results are discussed.
