Magnetohydrodynamic laminar boundary-layer flow over a wedge, the flow being subjected to a velocity caused by suction or injection, is studied. The fluid is assumed to be viscous, incompressible, and electrically conducting with a magnetic field applied transversally to the direction of the flow. The governing partial differential equations of this problem, subjected to their boundary conditions, are solved numerically by applying an efficient solution scheme for local nonsimilarity boundary-layer analysis. Numerical calculations, up to the third level of truncation, are carried out for the different values of the dimensionless parameters in the problem and an analysis of the results obtained show that the flow field is influenced appreciably by the applied magnetic field. Resume : Nous etudions 1’ecoulement magnetohydrodynamique de couche limite laminaire autour d’un fil (wedge) quand il est soumis a une injection ou succion de vitesse. Le fluide est suppose etre visqueux, incompressible et conducteur electrique et le champ magnetique est applique perpendiculairement e la direction de 1’ecoulement. Les equations differentielles du probleme considere avec les conditions aux limites associees vent resolues en appliquant un schema numerique efficace pour 1’etude locale non-similaire de couche limite. Des calculs numeriques jusqu’ au troisieme niveau de tronquation vent effectues pour differentes valeurs des parametres sans-dimension du probleme et 1’analyse des resultats obtenus montre que le champ d’ ecoulement est considerablement infuence par le champ magnetique applique.
