    Abstract

    A thermodynamic theory for dielectric and magnetic relaxation phenomena in polarizable and magnetizable fluid mixtures consisting of $n$ chemical components among which $r$ chemical reactions are possible is developed. Using the general methods of non-equilibrium thermodynamics a polar and an axial vector field are introduced as internal thermodynamic degrees of freedom in the entropy in order to investigate the possibility of cross effects among dielectric and magnetic relaxation and heat conduction, electric conduction, diffusion flow, viscous flow and chemical reactions. The phenomenological equations for these irreversible processes are formulated. The symmetry relations and the Onsager-Casimir reciprocity relations for the phenomenological coefficients are derived. The Curie principle is stated and among other things it is seen that, if the fluid mixture under consideration is isotropic with respect to all rotations and to reflections of the frame of axes (isotropy under all orthogonal transformations), there are no contributions in the expression for the entropy production due to the cross effects among magnetic relaxation phenomena and the other irreversible phenomena.
