This article’s purpose is to analyses the influence of magneto hydrodynamics on mixed convection in concentrated, vertical channel with heat production and absorption occurring internally. The governing coupled as well as nonlinear equations are analytically solved with a small-value-appropriate regular perturbation approach, and the solution obtained for concentration, temperature, and fluid velocity for heat production and absorption is described with the use of plotted graphs. Multiple temperatures are maintained throughout the length of the channels. The result of the velocity temperature with MHD and concentration are revealed.
