The generalization of the global evolution criterion of nonequilibrium thermodynamics of micropolar media in the case of nonvanishing electromagnetic fields is derived. Interaction with the environment is modeled by the black-body radiation. Application of the criterion to liquid crystals in equilibrium state is given and the complete set of fundamental equations is derived.en530 Physikmechanical fieldthermal fieldelectromagnetic fieldglobal evolution criterionblack-body radiationnonequilibrium thermodynamicsinteractioncrystalArticle1437-4358
