In this paper, we study the form of the inductor for producing a magnetic field in a superconductor bulk by using a method of PFM (Pulsed Field Magnetization). We tested two inductors: vortex coil and systeme of three coils, where we found the best results with the systeme of three coils. After that, we presente two processes for trapping a magnetic field in the bulk: direct magnetization and successive magnetization where we found similar results.
