This study examines the effect of Hall current on steady MHD flow past a moving vertical plate whereby magnetic fields is applied at an angle α with mass diffusion. The fluid considered is viscous, electrically conducting and incompressible. The velocity profile have been studied for different parameters like angle of inclination of magnetic field, Schmidt number, Hall parameter, magnetic field parameter, Mass Grashof number and time. The fluid model under consideration has been solved by using forward finite difference for the first order time derivative and central finite difference for the first and second order partial derivatives. The model contains equations of motion, diffusion equation and equation of energy. To analyze the solution of the model, desirable sets of the values of the parameters have been considered. The numerical data obtained is discussed with the help of graphs and table. It is found that the values obtained for velocity, concentration and temperature are in concurrence with the actual flow of the fluid. The motive of this study is to analyze the Hall Effect in the model. In the study it’s found that the inclined magnetic field angle and time decreases the fluid flow. The effects of parameters are shown graphically for different parameters. The results are found to be in good agreement and the data obtained is in concurrence with the actual flow phenomenon.
