11.4 Energy Storage. In the conservation theorem, (11.2.7), we have identified the terms E P/ t and H o M / t as the rate of energy supplied per unit volume to the polarization and magnetization of the material. For a linear isotropic material, we found that these terms can be written as derivatives of energy density functions.
