Simulation of High Temperature Superconducting Bulks Magnetized by Pulsed Field Magnetization with an Electromagnetic-Thermal Coupled Model [PDF]
, 2015 High temperature superconducting (HTS) bulks can be magnetized to become powerful trapped field magnets (TFMs), which are promising for high-performance electrical applications. To magnetize such TFMs, pulsed field magnetization (PFM) is supposed to substitute field cooling (FC) to provide in situ magnetization. However, the heat generation during PFM,
