Abstract Heat transfer in ferromagnetic stretching flow by moving surface considering a magnetic dipole is elaborated in current research. Rheological relations of non-Newtonian (Williamson) fluid are taken into account for modeling and analysis. Chemical reactions (homogeneous and heterogeneous) are considered for elaboration of mass transportation characteristics. Governing flow expressions are reduced to ODEs by implementing transformation procedure. The well-known bvp4c scheme is used for nonlinear systems computation. Influences of sundry parameters like ferrohydrodynamic interaction parameter, Weissenberg number, homogeneous-heterogeneous reaction parameters, Prandtl number and heat generation parameter on velocity, thermal and solutal fields in addition to coefficient of skin-friction and Nusselt number are displayed via graphs and tabular values. It is revealed that velocity and thermal fields have opposite behavior for ferrohydrodynamic interaction parameter. Besides the heat transportation rate is improved subjected to larger Prandtl number.
