Among other non-Newtonian fluid models, power-law fluid has gained much acceptance because of its some powerful applications such as pressure drop calculation in the drilling industry, utilization of blood flow for red cells in plasma and static as well as dynamic filtration. The aim is to analyze theoretically the steady three-dimensional boundary layer flow near the stagnation point and heat transfer of power-law ferrofluid over rotatory stretchable. The effect of Lorentz force on the flow and the influence of nonlinear thermal radiation upon the temperature is also incorporated. For this phenomenon, magnetite (Fe3O4) is considered as ferrofluid particles which are mixed with the base fluid (water). Physically modeled partial differential equations (PDEs) are lessened to ordinary differential equations (ODEs) by the support of precise similarity transformation and then the shooting method is implemented to obtain the solution of the resultant ODEs. A comprehensive tabular comparison between present and previously existing outcomes is made. From an overall exploration it can be concluded that the cross-sectional flow for shear thinning and shear thickening is examined upon increasing the concentration of the nanoparticles and flow behaving index of power-law. The Lorentz force retards the flow near the disk due to which velocity components decrease. Also, the temperature escalates for nonlinear radiation and this escalation is more prominent for shear thinning. Furthermore, the Prandtl number helps in controlling the boundary layer thickness.</p
