This numerical study documents the phenomena of heat transfer natural convection in a square porous cavity with corner heating and magnetic field.

The finite difference technique with Gauss-Siedel method is used to solve the governing equations with aid of (Over Relaxation) technique of a range (1.1-1.3).

The governing parameters are modified Rayleigh number, Hartmann's number, inclination angle of magnetic field and dimensionless length (non- dimensional heating region in both directions (x,y)) .

It was concluded that increase in the Hartman number leads to a decrease in the average Nusselt number while the increase in the modified Rayleigh number increases the average Nusselt number .The increase of dimensionless length (h) led to an increase the average Nusselt number .

However, the optimum reducing of the heat transfer rate was obtained at a large magnetic field in the horizontal direction
