Two fundamental theories are discussed in this paper. In the nonlinear electro–magneto–elastic analysis, different authors give different formulas. It means that the fundamental theory should still be studied. In this paper, we give a review of different theories and extend the physical variational principle to the material with electromagnetic body couple. For the temperature wave, we compare the inertial entropy theory and the Cattaneo–Vernotte’s theory in detail and show that the former is more appropriate. These theories may be interesting and need further research.
