| Abstract: | The propagation of waves in an absorptive medium is accompanied by unidirectional motion of this medium — a flow which develops due to the fact that the wave loses a portion of its momentum along with energy loss. It is this loss which is compensated by the flow by virtue of the momentum-conservation law. In a conducting medium the momentum losses via the waves are associated not only with the viscosity and thermal conductivity but also with the Joule-heat losses. Moreover, the magnetic field itself also affects the configuration and character of the flow in this case.Translated from Zhurnal Prikladnoi Mekhaniki i Tekhnicheskoi Fiziki, No. 4, pp. 30–33, July–August, 1970.The authors thank N.
