In order to deal with many scientific and technological problems such as solar dynamo and planetary problems, magnetohydrodynamics power-generation, plasma confinement, crude oil purification and rotating magnetic stars, we have investigated the steady flow of incompressible, viscous, conducting and optically thin fluid over a vertical plate with magnetohydrodynamic mixed convection, thermal radiation and viscous dissipation. The solution of governing partial differential equations is obtained by the spectral quasi-linearization method. Apart from finding solution for the induced magnetic field, velocity, and temperature, we have plotted graphs of skin friction and heat transfer coefficients for different pertinent parameters which are mentioned thereat. Results indicate that viscous dissipation has tendency to increase the temperature, induced magnetic field and velocity profiles whereas radiation parameter has opposite effect on it. Viscous dissipation and thermal buoyancy force tend to enhance the skin friction and reduce heat transfer coefficient. However, radiation parameter reduces skin friction and enhances heat transfer coefficient at the surface.
