Abstract We consider the problem of shock-wave incidence on a “magnetic wall”, which has been studied in [1]. It is shown that the dynamics of the processes which take place in this case depend significantly on the behavior of the conductivity-temperature dependence σ(T) of the medium and also on the magnitude of the magnetic-field intensity H0. An exact solution of the problem is constructed for a special form of the law σ(T). For an arbitrary law σ(T) the problem is studied numerically by means of digital computer computations; the results are compared with the exact results. Analysis of these solutions shows that the dissipative properties of the medium (electrical conductivity, viscosity), which determine the structure of the refracted wave front, affect the nature of the entire flow as a whole. The formulated problem also makes it possible to clarify the characteristic features of the decay of a discontinuity in a conducting medium.
