Abstract : A first order theory is developed to describe the motions of electrons and ions in a weakly ionized gas in the presence of a magnetic field when the gas is disturbed by the passage of a low-frequency wave such as an internal gravity wave. The theory includes the effects of electron-ion coupling through the elastic electron-ion collisions, nu ei. The approximations are believed to be compatible to the case of an internal gravity wave in the F1 and F2 levels of the earth's ionosphere. The results of the theory are compared to the results of the uncoupled theory (nu ei identical with 0). Calculations for a number of special cases indicate that the coupled theory must be used in the F region for all velocity components other than the vertical motion of the electrons. This component is adequately described by the results of the uncoupled theory for all cases of practical significance. (Author)
