We generate recombining nitrogen plasma plume by expansion of nitrogen arc into lower pressure vessel with a weak longitudinal magnetic field in a steady state. Spectroscopic observation reveals that the plasma has almost no component of molecular band spectra. Meanwhile, atomic nitrogen lines are observed with considerable intensity. The reason for this spectroscopic peculiarity is discussed in terms of chemical thermodynamics of the nitrogen thermal arc plasma and of non-equilibrium characteristics.We also examined the dynamic characteristics of the nitrogen plasma. We experimentally examined its acceleration phenomena and potential drop along the open magnetic field line flowing supersonically. We found that admixture of nitrogen into helium increases the flowing velocity and moderates the potential drop.
