This paper studies the effects of radiation on the flow near the two-dimensional stagnation point of a shrinking sheet immersed in a viscous and incompressible electrically conducting fluid in the presence of an applied constant magnetic field. The external velocity and the stretching velocity of the sheet are assumed to vary linearly with the distance from the stagnation point. The transformed governing differential equations are solved numerically by using the spline functions. The solutions are studied for a range of magnetic parameter, radiation parameter, Prandtl number, etc. The effects of these parameters are examined on the velocity and temperature distribution of the fluid, which are presented by graphs. The results exhibit that, by applying a strong magnetic field, the reverse flow can be reduced due to the shrinking sheet of shrinking sheet. The magnetic field increases shear stresses and decreases thermal boundary layer thickness. The thermal boundary layer becomes thinner with increasing values of the radiation parameter.
