Topic: Formation and dynamics of plasma streams generated by magnetoplasma compressor under external magnetic field. Object of research - plasma flows generated by MPC; the compression zone formed in the plasma flows generated by the MPC. The purpose of the research is to obtain experimental data on determining the effect of the external longitudinal magnetic field in the channel of a powerful quasi-stationary plasmadynamic device on the main characteristics of the plasma flow outside the accelerating channel. Main results: The influence of the external longitudinal magnetic field in the discharge channel of the magnetoplasma compressor (MPC) on the dynamics of plasma flows and the process of formation of the compression zone was studied. For the first time, spatial distributions of electromagnetic forces and electric potential in a self-compressed plasma flow in the presence of an external magnetic field were obtained. It was shown for the first time that the application of an external magnetic field leads to a decrease in the number of current vortices, an increase in the volume of the compression zone and Ampere's force. The dynamics of the structure, which is similar to the neutral current sheet, was studied. The obtained results reveal the possibility of a significant increase in plasma compression in the MPC and make the use of the MPC promising for experimental modeling of astrophysical phenomena.
