An analysis of MHD power-law fluid over a stretching/ shrinking surface in a non-linear Darcy-Forchheimer porous medium has been considered. The study includes the influence of Joule heating, viscous dissipation and heat source. The MATLAB in built bvp4c method has been used for the solution of the consequential non-linear differential equations. Influence of relevant physical parameters on velocity, temperature distribution and skin friction are discussed for pseudoplastic and dilatant fluid. It is noticed that the local Forchheimer parameter and power-law parameter helps to reduce the fluid velocity, while Eckert number raises the fluid velocity. Also, decrease in rate of strain is seen when the values of power-law parameter, local Forchheimer parameter and stretching parameter enhances in the pseudoplastic and dilatant fluid.
