Performances of the controlled active magnetic bearings can be sufficiently improved with the exact knowledge of the bearing force in the entire operating range. Therefore the magnetic force calculation of the laboratory implementation of a radial magnetic bearing, using 2D finite element method, is presented in the paper. Two methods for the force calculation are used, where both, i.e. the Maxwell stress tensor method and the virtual work method, give very close results. The verification of the bearing force calculation is performed by their comparison with measurements. The obtained results make it possible to perform a robust control design in the entire operating range.
