The flow structure around pulsed surface arc discharge in a transverse magnetic field is described. It is shown that the motion of the plasma channel leads to the formation of a toroidal vortex. In this case, the characteristic rate of gas inflow to the model wall in the aerodynamic wake of the arc was 30–50 m/s and corresponded to a value of up to 40% of the maximum gas expansion rate in the loading phase.
