Abstract

Experimentally, the changes of the longitudinal and transverse components of the magnetization intensity and the corresponding trapped field with time were measured simultaneously at low temperatures, in the courses of pulse magnetization and when HTS permanent magnet was subjected to small AC-field disturbances, respectively. Experimental results showed the presence of strongly correlated in- and out-of-plane flux motion in the context of flux cutting and reconnection. Combined with flux dynamics and flux-pinning mechanism of HTS, the anisotropic characteristic on the change pattern, the magnetic stability and energy dissipation of the trapped field were preliminarily discussed in the paper.
