Full 3-D time-dependent electromagnetic model for Roebel cables

This model was shared by V. Zermeno, Karlsruhe Institute of Technology. This model simulates the current distribution in the superconducting layers of a Roebel cable composed of 14 strands and estimates its AC losses. The mode is rather general and allows considering the cases of curr …

2-D axisymmetric and 3-D models for magnetization of superconducting bulks

Magnetic vector potential Current density distribution This model was shared by M. Ainslie, University of Cambridge. The first model is for a 2D axisymmetric bulk with zero field cooling (ZFC) magnetization. Here, the external magnetizing field is applied along the z axis – perpendicu …
