The balance equation for the space charge caused in a magnetized plasma by the action of a magnetic field on the parameters of the motion of electrons and positive ions is obtained and analyzed. As a zeroth approximation, a homogeneous plasma with zero space charge is used. In contrast to the calculation results, which takes into account the diffusion of charged particles with zero space charge and leads to a homogeneous balance equation for the electron concentration, the balance equation for space charge obtained is an inhomogeneous differential equation, since the inhomogeneity factor associated with the magnitude of the magnetic field is taken into account. The analysis shows that the profile of its transverse distribution differs from a similar distribution profile of charged particles of a homogeneous plasma and is determined by the boundary conditions on dielectric walls, the parameters of a homogeneous magnetized plasma, and depends on the nature of the gas and its pressure.
