Abstract :
We propose a perturbation technique of the discrete mixed formulation of H-oriented magnetostatics in an unbounded domain. We only keep the degrees of freedom of the magnetic field. We show that this method is more robust than the one obtained by perturbing the continuous problem. Moreover, we show that it is competitive with the direct solution of the initial mixed problem
