•The unsteady 2D radiative flow of an electrically conducting, non-compressible Maxwell fluid above a stretching surface is modeled.•Numerical solutions are obtained using the fourth-order Runge-Kutta method combined with the shooting technique in MATLAB.•The effects of heat generation/absorption and viscous dissipation are considered.•Unsteadiness, as well as suction/blowing parameters, reduce both velocity and temperature.•The Maxwell and magnetic parameters tend to decrease the local skin friction coefficient. The present article aims to investigate the unsteady flow of a Maxwell fluid over a stretching surface in a porous medium under the influence of a magnetic field and Joule heating. The efficacy of a heat source/sink, radiation, and dissipation is also taken into account. The governing equations are transformed into a set of ODEs using similarity variables and are solved utilizing the shooting approach in combination with the RK-4 method in MATLAB. The results are validated through comparison with existing literature. Velocity, temperature, friction coefficient, and Nusselt number are calculated for a range of selected parameters. Key conclusions reveal a decrease in the fluid's flow speed with increasing unsteady and suction parameters. Additionally, temperature increases with higher radiation and magnetic parameters. These findings may have significant applications in various energy systems and manufacturing processes.
