摘要：

in this paper, three methods for local error estimation to adaptive mesh generation in finite element method are tested and compared. In the two first the errors are estimated from boundary conditions violation at the borders of the elements. In the third method, the error estimation is reached from perturbation in the magnetic induction B. Two examples are used to test the three methods: The magnetostatic analysis of a contactor and the calculation of forces exerted by permanent magnets.
