The intention of this communication is to explore the significance of electromagnetohydrodynamic (EMHD) on the fluid transport properties of a chemically reacting nanofluid with two types of geometries. Simulations have been done to investigate the controlling equations by utilizing Crank-Nicolson scheme. Influence of embedded parameters such as Hartman number, heat source/sink, Brownian diffusion, chemical reaction, and thermophoretic diffusivity is graphically presented. Tables demonstrate the significant impact of sundry parameters on skin friction factor and heat and mass transfer rates. It is observed that the electrical field parameter has high influences on the fluid flow and heat transfer characteristics. © Springer Nature Switzerland AG 2019.
