The paper has dealt with two problems of calculation of electromagnetic force/torque. The first one is for magnetically anisotropic and conductive region. It has been presented sufficient condition for surfaceintegral representation of electromagnetic force/torque in conductive and anisotropic region. The second approach deals with the problem of independence of force/torque calculated value from shape of integral-surface. The second theorem gives the sufficient condition for this independence for Maxwell stress tensor method is applied.
