Analysis of Trapped Magnetic Field During Magnetization Process by Using SPA Method of Bulk Superconductor
Résumé
Trapped magnetic field is analyzed during magnetization processes of bulk superconductor by sequential pulsed field application method at low cooling temperatures of 44 and 20 K. Calculations are performed by solving the nonlinear transient A-V magnetic equation coupled to the heat equation thanks to a control volume method. The influence of the pulse number of the external magnetic field on the trapped field in the superconductor is presented.
