The effect of variable viscosity and thermal conductivity of the two dimentional stagnation point flow of an incompressible non-Newtonian micropolar fluid impinging on a permeable plate in presence of magnetic field is investigated. By means of similarity transformation the governing equations are reduced to boundary value problem of nonlinear coupled ordinary differential equations and solved numerically. The effects of different dimensionless parameters such as temperature dependent viscosity parameter and thermal conductivity parameter, microrotation parameter, Prandtl number etc. on flow and heat transfer has been studied. The results are presented graphically for velocity distribution, temperature distribution and micropolar distributions for various values of non-dimensional parameters. It is found that the effects of the parameters giving variable property of viscosity and thermal conductivity are significant.
