At first the special features of the inductive‐hydrodynamic type of an electromagnetic shock tube are sketched. The fast plasma flow in its expansion tube is homogeneous and free of eddy currents and distributed magnetic microfields. Therefore, it can be used for magneto‐plasmadynamic studies. Modelling of MHD channels with electrodes at the wall is very difficult because of electrode effects in the low‐pressure regime in use. Therefore, electrode behaviour in low‐pressure plasma streams has been studied extensively and results are given shortly. Modelling of electrodeless MHD channels by means of the inductive‐hydrodynamic shock tube is possible. We concentrated our work on a channel with ring‐shaped cross section and radial magnetic field. The results of studies on dynamics and electrodynamics in this type of channel are given.
