The current problem focuses on the heat transfer analysis of non-Newtonian Prandtl-Eyring fluid flow under an applied magnetic field over a variable stretching sheet. is assumed because most practical situations have surfaces. In addition, very important phenomenon in many applications like extrusion sheets, cooling plants, etc. Thus, estimated with Christov-Cattaneo conduction law to get more realistic results. physical mathematically modeled all these assumptions, it yields boundary value coupled nonlinear partial differential equations. governing equations are first transformed into ordinary by employing set similarity transforms. And, obtained system numerically simulated shooting method for different parametric conditions. proposed algorithm quite efficient and implemented solve efficiently. Variations momentum thermal energy captured graphs varying govern parameters. surface drag coefficient reduced Nusselt number computed analyzed. For validation results, comparison established existing literature, can be shown that results matched well reported literature. It observed both parameters (α,β) effects velocity i.e. parameter α increases while β decelerates it. Also, produces Lorentz force which works opposite direction hence motion significantly. higher this less favorable movement as compared linear stretching. temperature cools down if relaxation considered.
