The Grad 13‐moment method (using separate zero‐order species flow velocities and temperatures) is used to calculate the electron traceless pressurePeand heat flowqefor a weakly ionized gas in a dc magnetic field. Electron‐neutral collisions are assumed to dominate and the “transport approximation” is used to obtain expressions forPeand qeusing arbitrary inverse power interparticle force laws. The results, under most conditions, show terms that are similar to the usual expressions for a simple gas except that the electron viscosity and thermal conductivity involve the electron‐neutral collision frequencyvenrather than the electron self‐collision frequency. In addition, there are terms inqeproportional to any differences in the zero‐order electron and neutral flow velocities and temperatures. Finally, it is noted that the electron‐neutral interparticle force law has very little effect on the form of the results (although it is important in determining the explicit value for&ngr;en).
