A two-dimensional steady convective flow of a micropolar fluid past a vertical porous flat plate in the presence of radiation with variable heat flux has been analyzed numerically. The local similarity solutions for the flow, velocity profile, microrotation and heat transfer characteristics are illustrated graphically for various parameters entering into the problems. The effects of the pertinent parameters on the local skin friction coefficient, plate couple stress and the heat transfer are also calculated. Effect of variable electric conductivity and constant electric conductivity has been analyzed numerically for the skin friction coefficient and rate of heat transfer. The result shows that for Magnetic field parameter, Prandlt number, temperature dependent heat source (or sink) parameter and space dependent heat source (or sink) parameter, the variable electric conductivity is high pronounced than that of constant electric conductivity for micropolar fluid for both the case of skin friction coefficient and Nusselt number.
