Abstract :
In this paper, the authors compare the numerical results obtained from a strong formulation using finite difference schemes (FDS) and a weak formulation using finite element method (FEM). The main purpose of our study is to know which method computes accurately the distribution of magnetic field in an experimental device. Numerical results are compared with a set of experimental data.
