Electrodynamics, gravitation and spin
Abstract
Using a kinetic model, the Einstein and Maxwell field equations are formulated for the case of a medium whose particles possess internal spin. The physical meaning of the extended field equations can be understood from a general relativistic extension on the Lorentz theory of dielectrics.
