Abstract: The effect of a magnetic field, B, on heat flow in a gas in an intermediate pressure range has been studied. The ratio of the heat flow changes in the fields B ⊥ ▿T and B ‖ ▿T was found to change nonmonotonically with pressure in N2 and CO. With the decreasing pressure, a difference is observed between the dependence of heat flow on field orientation and the corresponding angular dependence in the limiting case Kn→0 (Kn = l/L, l is the mean free path, L is the geometric size). An expression has been obtained for the heat flow in a magnetic field for Kn ≲ 0.1 from the solution of an integral kinetic equation. In particular, it has been shown that the special features of the Senftleben-Beenakker effect observed with the decreasing pressure arise not only due to spherically symmetric molecule-surface interaction, but also to nonspherical scattering on walls.
