| Abstract: | In this paper the electro-magnetic heat conduction laws for electromagnetic metal materials are derived from the Boltzmann equation with the aid of approximation of free electron in slow-change field. With the energy equation and the equation of elasticity theory, several special multi-field coupling basic equations of electro-magneto-thermoelasticitys, such as the parabolic, hyperbolic and dual-phase-lag equations, are suggested. |
