The theoretical examination of the effects of velocity, temperature, concentration parameter variations and magnetic fields on convective periodic flow was studied on an electrically conducting, viscous and incompressible fluid through a porous medium in an inclined plane. A set of coupled ordinary differential equations arising from the formulation of the problem were solved analytically by method of undetermined coefficient. The solution to the problem is obtained thereafter and with realistic parameter values the results were displayed in plots. The effects of parameter variations on velocity, concentration and temperature fields were discussed with the help of the plots. From the plots, the following results have been drawn; it is observed that increase in the Prandtl number decreases the temperature, increase in the Reynolds number decreases the temperature of the fluid, Reynolds number decreases the concentration of the fluid, increase in the Schmidt number decreases the concentration making it more significant at the centre of the flow region, increase in permeability leads to increase in the velocity and increase in the magnetic field leads to decrease in the velocity.
