In this paper, numerical simulations of trapped field and temperature rise in a bulk superconductor during magnetization process are studied. The pulsed field magnetization method and the modified multi-pulse technique with stepwise cooling are presented. We adopt the control volume method for solving the thermomagnetic system describing the physical phenomena. The electromagnetic fields and temperature are computed because of an explicit algorithm. The results are compared with published experimental results and show a good concordance.
