Abstract

A new method to calculate three dimensional current distributions in twisted superconductors is proposed in this paper by introducing the twisted coordinates together with periodic boundary conditions. Numerical analysis is performed based on the critical state model, by which the current distributions in type-II superconductors can be calculated. Numerical results indicate that the longitudinal currents are induced in the normal conductor region when the relatively large longitudinal magnetic flux is applied
