Abstracts:

When investigating the influence of magnetic field on the supersonic flow about the model equipped with the electromagnetic facility it is found that there exists an appreciable dependence of the shape of the gas discharge and the frequency of its rotation on the polarity of connection of the electromagnetic facility with the external voltage source. With the aim of elucidation of the main mechanisms governing the discharge dynamics in the solenoidal magnetic field we conducted experiments in a quiescent gas. The main means of diagnostics in these experiments was digital high-speed recording of the gas discharge rotating in the magnetic field. A factor is found which is conditioned by reverse (abnormal) motion of the cathode sport and was not taken into account earlier. Just this mechanism governs the discharge dynamics when changing the polarity of connection of the electromagnetic facility with the external voltage source.
