           The paper deals with the effect of heat source on steady flow of a viscous incompressible fluid over a heated stretching sheet with temperature dependent viscosity. A magnetic field of uniform strength is applied normal to the flow. In order to establish a finite condition z®1 instead of an infinite boundary condition, the governing equations in non-dimensional form are transformed to new system of co-ordinates, in which the equation of motion is a non-linear ordinary differential equation that is linearised by Quassi-linearisation method. Then they are transformed to system of linear equations using finite difference formulae for which a numerical code is executed using C-program.

 The results for the velocity, temperature, Skin friction and Heat transfer are discussed and analysed.From this study, it is found that the temperature and velocity of the fluid increase in the presence heat source.

Keywords: Steady flow, heated stretching sheet, heat source, Quassi-linearization and finite difference methods.
