In a rectangular box, containing a rarefied polyatomic gas, the combination of a temperature gradient and an external magnetic field can cause a slip velocity of the molecules along the wall. This slip gives rise to a pressure difference across the box: the thermomagnetic pressure difference. Experiments have been performed on N2, HD, CO, CO2, CH4, CF4 and SF6 at room temperature. Moreover the dependence of the effect on the angle between temperature gradient and magnetic field was studied. Good agreement with theory was found for all gases, except for HD.
