Simultaneous impacts of non-linear radiation and magnetohydrodynamics in Marangoni convection nanoliquid, as well as novel aspects of activation energy and space dependent heat source are addressed. Nanoliquid attributes include Brownian movement and thermophoresis diffusion. An NDSolve base shooting technique is employed for the numerical simulation. Aspects of various embedded variables are focused on velocity, heat and mass transport distributions via graphical interpretations, and temperature gradient at the surface is estimated and analyzed. This study identified that the Exponential based Space Heat Source (ESHS) parameter significantly enhanced the thermal field. Activation energy and temperature difference parameters decrease the nanoparticles concentration. Also, temperature gradient enhances for higher Marangoni ratio parameter, Hartmann number, dimensionless activation energy and thermophoresis parameter.
