A comprehensive study of the steady laminar flow with heat generation of an incompressible electrically conducting micropolar fluid impinging on a permeable flat plate is analyzed numerically. A uniform suction or blowing is applied normal to the plate, which is maintained at a constant temperature. Also, a uniform magnetic field is applied normal to the plate and the viscous dissipation effect is taken into account. The governing partial differential equations are transformed into ordinary differential equations by using similarity variables and then solved them numerically by standard technique. The effects of the uniform suction/ blowing parameter, magnetic parameter, material parameter on the flow and heat transfer are presented graphically and discussed
