  We study the diffusive expansion for solutions around Maxwellian equilibrium
and in a periodic box to the Vlasov-Maxwell-Boltzmann system, the most
fundamental model for an ensemble of charged particles. Such an expansion
yields a set of dissipative new macroscopic PDE's, the incompressible
Vlasov-Navier-Stokes-Fourier system and its higher order corrections for
describing a charged fluid, where the self-consistent electromagnetic field is
present. The uniform estimate on the remainders is established via a unified
nonlinear energy method and it guarantees the global in time validity of such
an expansion up to any order.
