This paper presents a validation of the hybrid method using the H and A formulations for Pulsed Field Magnetization (PFM). This hybrid method can help for simulating more complex problems involving superconductors, electric circuit and/or ferromagnetic materials. In some cases, the hybrid method can even speed up the simulation compare to the model that is based on H formulation only. A 2D axisymmetric model of PFM coupled with electrical circuit is first considered. To validate our concept, we simulated the same model governed by the hybrid method and the H formulation. The comparison of the final trapped magnetic flux density is then performed. The hybrid method was faster around 46 %. In the final paper, the validation and comparison will also be made on a 3D problem.
