Moment equations are obtained from the Boltzmann equation for a conducting gas in electric and magnetic fields. Relatively simple stress and heat-flux equations yielding one-fluid description of a slightly ionized gas mixture are obtained. The associated boundary conditions are obtained by applying conservation laws near the wall. These moment equations and boundary conditions, together with Maxwell' s electromagnetic equations and their boundary conditions, form a determinate system to describe the dynamics of a rarefied conducting gas in electric and magnetic fields. This system includes, as limiting cases, both the thirteen-moment equati ons for rarefied gases and the continuum magneto-gas-dynamic equations. (auth)
