The problem of unsteady free convection MHD flow of an incompressible viscous electrically conducting fluid under the action of transverse uniform magnetic field between two heated vertical plates is formulated here keeping one plate adiabatic. The governing equations of velocity and temperature fields with appropriate boundary conditions are solved by the Integral Transform Technique. The obtained results of velocity and temperature distributions are shown graphically and are discussed on the

... asis of it. The effects of Hartmann number, Prandtl number and the decay factor, and effects of adiabatic plate on the velocity and temperature fields are discussed.
