The present study examine the influence of an inclined magnetic field on micropolar Casson fluid over a stretching sheet. Viscous dissipation effects are also taken into consideration. The governing physical problem is presented using the traditional Navier-Stokes theory. By means of a scaling group of transformation, the consequential system of equations is transformed into a set of nonlinear ordinary differential equations which are then solved using an implicit finite difference approximation (Keller box method). The working fluid is examined for several sundry parameters graphically and in tabular form. It is observed that with an increase in inclination angle, the velocity profile decreases while temperature increases. The Eckert number enhances flow velocity and temperature, whereas it decreases shear stress at the wall and heat transfer rate. The rheological fluid parameter contributes to the decline of velocity and temperature for weak as well as for strong concentrations of micro-elements.
