Nonlinear effects of planar and quasi-planar magnetosound perturbations are discussed. The plasma is as- sumed to be a Newtonian thermoconducting gas with infinite electrical conductivity permeated by a magnetic field orthogonal to the trajectories of gas particles. Generation of the non-wave modes (magnetoacoustic heating and streaming) in the field of periodic and aperiodic magnetoacoustic perturbations is discussed. The results are compared with acoustic heating and streaming in an nonmagnetized Newtonian gas. In contrast with a Newto- nian gas, the magnetoacoustic forces of heating and streaming are not proportional to the summary attenuation. The magnetoacoutic force of streaming is always smaller than the Newtonian one, but that of heating may take larger or smaller value in dependence on the magnetic streght
