@misc{Spałek_Dariusz_Two, author={Spałek, Dariusz}, howpublished={online}, language={eng}, abstract={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 surface-integral 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.}, title={Two theorems about electromagnetic force in activate anisotropic regions}, keywords={anisotropy, forced/active anisotropy, electromagnetic torque, solid rotor motor}, }
