**4. Conclusions**

In this work, the effects of entropy generation on power law nanofluid through a horizontal channel in a way that one wall is movable and the other is stationary are presented. The impact of a mixed convection magnetic field and an electrical double layer has combined for momentum conduct. Flow is produced in an axial direction by the movement of the upper wall. The important findings are:
