The development of cryo-magnets based on REBaCuO type superconductors that can generate up to 17 T requires the implementation of a magnetization system and therefore, it involves one or more coils around the superconducting materials. Currently, the most convenient way to magnetize a bulk High Temperature Superconductor (HTS) is to use a Pulsed Field Magnetization (PFM). It can generate strong magnetic fields while using a relatively compact and simple coil. Thus, bulk HTS can be directly magnetized, in situ, into the final application. In a previous work [1], we have studied and designed different coils in order to magnetize, using PFM, an inductor of a radial flux superconducting machine with one pair of poles. Each pole contains four HTS bulks that can be placed in a square or rectangular pattern. For a given primary source of energy, here a capacitor bank of 10 kJ (5 mF, 2 kV), the PFM process strongly depends on the inductance value of the coil used to magnetize because it defines the waveform of the current: the peak value and the time constant. Thus, a 3D modeling of the coil is required in order to be sure that the magnetic field produced will allow to fully magnetize the bulk HTS. From the practical point of view, we would like to achieve an average magnetization of each pole around 4 T. The maximal magnetic field applied to the sample is in the range of 6 to 10 T, Fig. 1, so such value seems achievable. In this paper, the induced currents and trapped fields in the bulk HTS for several geometries of poles will be studied by means of numerical simulations. Presented results will be the maximal trapped magnetic field of each bulk HTS, and the estimated magnetization of the poles of the inductor. References [1] K.
