To investigate the possibilities of magnetohydrodynamic (MHD) effects on a hypersonic flow structure, it is necessary to ionize the gas flow. It is possible to create a local region of conductivity of the flow using electrical discharges under experimental conditions. The paper considers the MHD interaction of a high-speed air flow and electrical discharges (high-voltage pulse and high-frequency) in a homogeneous magnetic field when flowing around test models. It is shown that the use of discharges in a magnetic field makes it possible to significantly change the shock-wave structure of the flow near a streamlined surface: to change the angle of the oblique shock, to generate new shock, to transform attached oblique shock to the bow shock. Systematization of the obtained data on the value of the hydromagnetic interaction parameter S characterizing the strength character of the observed effects is performed. Thus, S < 0.05 corresponds to the weak MHD-interaction, S = 0,05-0,15 - moderate MHD-interaction, S > 0.15 - strong MHD-interaction.
