Resumen
- Purpose – The paper aims to describe the coupling of magnetostatic finite formulation of electromagnetic field with two integral methods.
  
  Design/methodology/approach – The first hybrid scheme is based on Green's function applied to magnetization source while the other one is based on a magnetic scalar potential boundary element method. A comparison of the two techniques is performed on a benchmark case with analytical solution, on a 2D multiply‐connected problem and on an industrial case where measurements are available.
  
  Findings – The proposed hybrid approaches have proved to be effective techniques to solve open boundary non‐linear magnetostatic problems. Similar convergence speed with respect to the number of unknowns is found for both schemes Originality/value – The paper shows the effectiveness of hybrid schemes applied to the finite formulation, assessing their performances on various test cases.
