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 …
