Abstract
The Glansdorff-Prigogine linear stability theory of non equilibrium processes as well as the associated evolution criterion, are extended to polarized systems. The equilibrium stability conditions are derived from the negative definite form of the second differential of entropy. Additional inequalities are obtained giving rise to dipole stability conditions. The non equilibrium stability condition is formulated by using a Liapounoff function including both the second differential of entropy production and a negative term related to the electromagnetic energy. The explicit form is then calculated by means of the excess balance equations for mass and energy as well as the Maxwell equations applied to the disturbance of the electromagnetic field. When convection occurs, the excess balance equation for momentum is also required.
