The ambipolar diffusion column in a transverse magnetic field is treated with phenomenological theory. In the transverse magnetic field, the cross section of plasma column is a ellipse whose major axis is parallel to the magnetic field. The spatial distributions of electron density and current density are symmetry in regard to the minor axis and are asymmetry in regard to the major axis. For example, the distributions of electron density, current density and charge density on the minor axis are shown in Fig. 2, Fig. 3, and Fig. 5 respectively. In section 5, the equation of the internal energy is given and the electron temperature is determined.In sections 4 and 5, such behaviors of plasma column as movement of column, current-voltage characteristic and the relation between longitudinal electric field and transverse magnetic field are discussed.
