Abstract: Time-varying magnetic fields penetrate superconductive coils due to the finite interwire resistance and thereby cause eddy currents and losses. Specialized eddy-current models are developed which resolve the complicated current paths without necessitating the cable geometry to be meshed. An eddy-current model which directly relates the induced magnetization to the flux change is compared to eddy-current models which consider an additional mesh for discretizing the electric field at physical or numerical current redistribution zones. The presented techniques are applied to simulate the adjacency and crossover eddy currents occurring in Rutherford cables when submitted to ramped excitations.
