The paper has dealt with two theoretical problems of calculation of electromagnetic force or torque. The first problem considers the magnetically anisotropic and conductive region. The theorem about equivalence of both Maxwell and Lorentz methods has been presented. The second problem deals with the independence from the integration surface of force or torque calculated by the Maxwell method. The second theorem which presents the sufficient condition for an independence problem in the anisotropic and nonconductive region has been formulated.
