The flow of an electrically conducting and incompressible fluid at the forward stagnation point of an infinite plane wall is studied considering the effect of suction or of injection. On the assumptions of small magnetic Reynolds number and of zero electric field, it is found that the similar solution of boundary layer equations exists when a uniform magnetic field is applied normal to the wall and the velocity of suction or of injection are constant. The similar solution is expressed in a form of integral equation and obtained by iterative numerical quadratures. Numerical results for various values of parameters are given for the velocity profile, skin friction, displacement thickness and momentum thickness. Further, present numerical results for large suction or large injection are compared with those of asymptotic analysis. It can be concluded that an asymptotic analysis for large suction or large injection might be balid for K≥5 or K≤-3 and results be in good agreement with those of numerical calculations within a few percent, where K is a parameter of suction or of injection.
