Heat transfer plays a great role in engineering processes, blowing of fluids is used in designing thrusters and prevention of corrosion. Suction is used in film cooling and coating of wires in chemical engineering. A lot of research has based on thermal reduction in processing streams and forgetting the machine efficiency. The study theoretically investigates the effect of hall current on a steady magneto convection and radiative heat transfer over a porous plate. This work is motivated by the need to improve the machine efficiency in our industries. The transport model is of an incompressible fluid moving through a porous plate, magnetic field is applied perpendicularly to the plate, equations governing the flow are formulated then converted to higher order ordinary differential equations using the similarity transformation. The resulting ODE’s are solved using the fourth order Runge-Kutta method coupled with a shooting technique. The solutionare then executed using MAPLE computer programme and the results presented graphically. The results are then analysed putting into consideration their industrial and engineering applications. Increase in Prandtl number and Grashof number caused an increase in the fluid velocity but decreased the skin friction. Increase in magnetic field, radiation increased the fluid temperature distribution.
