Similarity solution of unsteady forced convection magnetohydrodynamic boundary layer flow and heat transfer over a porous stretching cone are analyzed. The governing partial differential equations are transformed into ordinary differential equations by using local similarity transformations. The transformed equations are solved numerically subject to the boundary conditions by using Nachtsheim-Swigert iteration technique along with the 4th order Runge-Kutta integration scheme. The numerical results are checked against previously published work for special cases of the problem in order to access the accuracy of the numerical method and found to be in good agreement. The results indicates that the fluid velocity decreases for increasing values of magnetic parameter, porosity parameter and unsteadiness parameter but the reverse results arises for pressure gradient parameter, material parameter and stretching ratio parameter. The heat transfer rate decreases for increasing values of stretching ratio parameter, material parameter, pressure gradient parameter but increases for magnetic parameter, unsteadiness parameter, porosity parameter, Prandtl number and wall temperature parameter. The numerical results are presented graphically and also in tabular form.
