This paper studies the unsteady laminar magnetohydrodynamic (MHD) mixed convection flow of an incompressible viscous non-Newtonian Casson fluid in the stagnation region of an impulsively rotating sphere. Nonsimilar solutions and the fourth order Runge-Kutta method are used to solve the partial differential equations governing the problem. The obtained results are presented in terms of the velocity profiles in the and directions, the shear stresses profiles in the and directions and the profiles of heat transfer rate. The outcomes of the paper indicated that as the Casson parameter increases, the velocity profiles in the direction increase, whereas it reduces the velocity profiles in the direction and temperature distributions. Additionally, the increase in the shear stresses in both the and directions can be obtained by increasing either the magnetic field parameter or buoyancy parameter.
