Abstract
The steady twodimensional magnetohydrodynamic free convective laminar flow of an electrically conducting viscous and incompressible fluid with finite electrical conductivity past an infinite heated vertical porous plate has been investigated The coupled ordinary differential equations governing the velocity the temperature and induced magnetic field distributions are solved analytically The effects of Prandtl number P r Grashof number Gr magnetic field parameter M and suction parameter overlineV 0 on the flow field are analysed using graphs The study reveals that the increase of the Prandtl number Pr and the suction velocity overlineV 0 lead to a decrease in the temperature velocity and the induced magnetic field in the boundary layer region whereas increase in Grashof number and magnetic field parameter lead to increased induced magnetic field
