Influence of an alternative/pulsed magnetic field on a YBCO bulk in an iron core

Résumé

We have studied the influence of an alternative, and of a pulsed magnetic field on a YBCO bulk in a symmetrical iron core using two copper coils at 77 K. In this experimentation, it was found that one reduction occurs on the trapped magnetic if an alternative field is applied at the first time. Furthermore, no other variation is observed if a new alternative field is applied with the same order of magnitude or less. A hysteresis curve was observed by using a pulsed field magnetization process, from a virgin state of the YBCO bulk to a fully penetrated state.
