Abstract: In this work we prove the correctness “as a whole” by the time of the initial-boundary value problems for the equations of motion of a viscous heat-conducting gas in view of the magnetic field. Showing the transition from the primary to the three-dimensional Euler equations and the subsequent Lagrangian coordinate variable. Proof of the main results was carried out at the same time to move to the cylindrical and spherical waves.

Keywords: the equations of the motion of the magnetic gas dynamics, boundary value problem, solvability, cylindrical symmetry, spherical symmetry, magnetic field.
