This study addresses heat and mass transfer under magnetohydrodynamic convection over a
vertical wedge submerged in a porous medium. The governing equations were non-dimensionalized and
solved numerically using the finite difference method. The effects of several physical parameters were
investigated, including the power-law index, inertia coefficient, buoyancy ratio, Lewis number, thermal
gradient coefficient, and Hartmann number, on velocity, temperature, concentration, and Nusselt and
Sherwood numbers. The results showed that increasing the buoyancy ratio enhances heat and mass transfer,
while increasing the inertia coefficient and Hartmann number reduces them. The results were validated by
comparing them with the Darcy case, where the error percentage was 0.045%, confirming the accuracy of
the numerical model.
