### Abstract

A new complete set of basic equations for magnetic fluids having good conductivity of heat and electricity with internal rotation has not been derived before. In this paper, governing equations for such conducting magnetic fluids are formulated by the thermodynamical method, in which free energy and the dissipation function are used on the basis of kinematical balance equations in the polar theory. A simple method for determining a constitutive equation of magnetization is proposed, so that the relaxation equation of magnetization becomes unnecessary.
