This work is focused on the implication of a partial magnetic field on a square cavity heated isothermally at the bottom wall and cooled at the sidewalls. The top wall is insulated. The enclosure is filled with electrically conducting fluid. The coupled transport equations are solved numerically using a written computing code adopting FVM and SIMPLE algorithm applying specific boundary conditions. The analysis is carried out for different involved parameters like Rayleigh number (Ra), Hartmann number (Ha), and angle of inclination ( γ ). The results are illustrated using contours of streamline, isotherms, and heat transfer characteristics. It is found that the flow structure, the temperature distribution is severely affected by the above-mentioned parameters. The rate of heat transfer is significantly reduced with the increasing Ha.
