This work concerns the wall plume of an electrically conducting fluid situated in a vertical free stream with a constant velocity. The flow is retarded by a uniform transverse magnetic field. The problem has been investigated in the past, but the results obtained previously are wrong because the momentum equation used is not appropriate. The results of the present work were obtained by direct numerical solution of the boundary layer equations taking into account the correct form of the momentum equation. The maximum difference between the results is 40% and increases further as the magnetic parameter increases. Taking into account this fact, these results essentially form the first solution to this classical problem.
