The propagation and damping of electromagnetic waves in isotropic media with electric conductivity and magnetic relaxation phenomena are investigated. Relaxatio phenomena are analyzed using a dynamical constitutive equation obtained by some authors with the help of non-equilibrium thermodynamics. This equation, which generalizes Snoek's equation, has the form of a linear relation among the magnetic induction and its first derivative with respect to time, the magnetization , the first and second derivatives with respect to time of . We derive solutions of the relaxation equation which also satisfy Maxwell equation and using the Laplace trasform we show as the solution obtained generalize the classical results.
