Abstrakt: The significance of non-Newtonian fluids is preferred for nanomaterials due to industrial demands. Consequently, this research examines the influence of magnetic fields and power law variation on nanofluids with heat transfer and heat source effects on a movable flat stretching surface assessing the nanoparticles effectiveness. Using numerical simulations via Runge–Kutta method, local similarity is used to convert partial differential equations into ordinary differential equations transformations to solve numerically and engage the local non-similarity method (LNS). The Mathematica package is used to calculate different parameters obtained in the solutions. The velocity and temperature are affected by different nanoparticles and parameters, and these effects are depicted graphically. The results obtained are compared to previous studies to confirm the inference. The output of this analysis shows that increasing the volume fraction of copper nanoparticles has a significant effect on thermal and momentum dispersion, while silver nanoparticles exhibited the maximum thermal conductivity, which is a substantial and obvious discovery regarding the increase in heat source. Furthermore, an increase in the volume fraction leads to a decrease in both the skin friction coefficient and Nusselt number. These findings have important implications for creating more efficient cooling systems for electronics and other industrial applications. [ABSTRACT FROM AUTHOR]
