It includes not only the electric moment calorific effect caused by a single electric moment entropy and the magnetic moment calorific effect caused by a single magnetic moment entropy, but also the electric moment-magnetic moment coupling calorific effect caused by the electric moment-magnetic moment coupling entropy. (2) This refers to the calorific effect due to the coupling between polarized electric dipoles and polarized carriers under the drive of the applied alternating electromagnetic field and its components. It not only includes the electric moment calorific effect due to a single electric moment entropy and the Joule calorific effect due to a single crystal lattice entropy and electron entropy, but also the electric moment-electrical conduction coupling calorific effect due to the electric moment-(crystal lattice + electron) coupling entropy.
