[en] The Korteweg-de Vries Burgers (KdVB) equation for magnetosonic wave propagating in the perpendicular direction of the magnetic field was derived for homogeneous electron-ion magneto-plasmas. The dissipation in the system was taken into account through the kinematic viscosity of the ions. The effects of kinematic viscosity of ions, plasma density and magnetic field strength on the formation of magnetosonic shocks were investigated. It was found that shock strength was enhanced with the increase in the plasma density of the system. However, the amplitude of magnetosonic shock was found to be decreased with the increase in magnetic field strength. The critical value of the dissipative coefficient to form oscillatory profile and monotonic shock was also discussed. The magnetosonic wave plays an important role of energy transport phenomenon in the laboratory and space plasmas. We had investigated monotonic as well as oscillatory shock in the electron ion plasma system by taking into account the plasma parameters from laboratory experiments. The strength of the non linear magneto sonic shocks in electron ion dissipative plasma diminishes with the enhancement of magnetic field intensity as shown. These results have direct relevance with space and laboratory plasmas. (orig./A.B.)
