In the present research work, the simultaneous effects of magnetic field and Hall current on an unsteady natural convective flow of incompressible, electrically conducting fluid towards a semi-infinite vertically inclined plate in presence of heat and mass transfer studied. For the numerical results, the basic governing non-linear partial differential equations converted into linear coupled partial differential equations using non-dimensional quintiles and are solved, numerically by finite difference method for velocity (both primary and secondary), temperature, concentration fields are discussed through graphs with the help of engineering parameters such as Grashof number for heat transfer, Grashof number for mass transfer, Prandtl Number, Schmidt Number, Hartmann number and Hall parameter.
