An analysis for heat transfer enhancement of Graphene oxide (Go)/Kerosene oil and Go + silver (Ag)/Kerosene oil hybrid nanofluid is made theoretically when the fluids flow through a porous medium over a stretching sheet in the presence of an applied magnetic field. The heat energy is augmented with thermal dissipation, heat source, and convective boundary conditions. The mass transpiration at the wall of the sheet is taken into account. The model equations are transmuted to ordinary differential form. The roles of controlling parameters are observed numerically by hiring Runge-Kutta method in Matlab coding. The flow speed becomes faster with Maxwell fluid parameter. The growing strengths of magnetic field and porosity resistance make the flow slower but cause to raise in temperature. Further, the additive volume fraction of silver with Graphene oxide becomes responsible to decelerate the flow and enhance heat transportation. The skin friction factor declines in magnitude against exceeding inputs of magnetic characteristic parameter M and porosity parameter Kp.
