Examining carefully the electrodynamics of moving media with velocity υ along the thought suggested by Trousdell and Toupin, it seems to be more profitable to define the electromotive force as E+υ×μ_0H, as well as the magnetomotive force as H-υ×εE inside matter. The equations of field given by these definitions and the fundamental laws of electro-magnetic induction lead easily to a symmetrical momentumenergy tensor of field and a relativistically invariant separation of etherial and material tensor, and the fundamental relation of thermodynamics can be derived. The field outside of matter and Faraday's low of electro-magnetic induction are not changed at all by those changes of definition. A few considerations on thermodynamical quantities are also added.
