N2 - There have been many studies that consider the effect of mixed convection on nanofluid that passes a magnetic object or not, whether it is a flat plate, solid sphere, or porous sphere. The implementation of those problems can be found in engineering and industrial fields such as nuclear reactors, pistons, oil drilling, chemical piping in factories and propulsion on ships. However, it has never been studied about object with magnetic sliced porous sphere. Therefore, we consider the effect of magnetic, porosity and slicing angle parameters towards velocity and temperature profiles of nanofluids when passes porous sliced magnetic sphere problem. Therefore, we develop mathematical model of the problem that consists of continuity equation, momentum equation and dimensional energy equation. Furthermore, Keller-Box method is used to solved the problem numerically. From the simulation, we obtain that the velocity of nanofluid flow become slower when magnetic parameter increases and the temperature of nanofluid flow become lower when the magnetic parameter increases. For porosity parameter, we obtain that with a greater porosity parameter value, the velocity of fluid flow is slower and the temperature of fluid is lower. For Slicing angle, we obtain that the velocity of the fluid increases with increasing slicing angle while the fluid temperature decreases.
