An analysis of steady two‐dimensional flow, of an electrically conducting fluid through a porous medium, occupying a semi‐infinite region of the space bounded by an infinite, vertical and porous limiting surface under the action of a transverse magnetic field is considered. Approximate solutions have been derived for the velocity and temperature fields and the rate of heat transfer (Nusselt number). The variations of the velocity and Nusselt number are shown on graphs.

A theoretical analysis of steady free convectivc and mass transfer flow is presented when a viscous, incompressible, and electrically conducting fluid flows through a porous medium occupying a semi-infinite region of the spacc bounded by an infinite vertical porous plate. A magnetic field of uniform strength is applied perpendicular to the plate and the fluid is subjected to a normal suction velocity while the hcat flux at the plate is constant. An analytic solution of thc problem is obtained and thc effects of a porous medium, a magnetic paramcter, as well as thc other paramcter entering into thc problem, are discussed and shown graphically. On presente une analyse thtoriquc de I'Ccoulcrnent dc convection librc et du transport de masse pour un fluide visqueux, incompressible et 6lectriquenlcnt conducteur traversant un milieu poreux qui occupc une rCgion semi-infinie born& par une plaquc poreuse verticale infinie. Un champ magnktiquc d'intensite uniforme est applique perpendiculairement B la plaque, et le fluide est soumis B une vitcsse de succion normalc. alors que la plaquc reqoit un flux dc chaleur constant. On obtient une solution analytique du probltme, et les effets du milieu porcux, du pararnttre magnktiquc. ainsi que de I'autre parametre entrant dans le probltme, font I'objct d'une d~scussion et d'une prisentation graphiquc.
