  Maxwell's equations incorporating thermoelectric and thermomagnetic effects
are studied. Energy transport involving electric field only flows along the
velocity direction and a direction perpendicular to it. Magnetic energy
transport associated with magnetic field only is found to flow along the
velocity direction and a direction normal to it. The temperature is transmitted
like an electromagnetic wave traveling at the speed of light. Thermoelectric
and thermomagnetic polarizations are induced in the medium that are directly
proportional to the temperature. An electronic transport due to temperature
variations only and without electric or magnetic field is found to be
accessible. Electric and magnetic fields due to temperature gradient are shown
to arise provided the photon is massive.
