Linear and nonlinear analyses in a pressure driven flow are performed numerically for an electrically conducting fluid between parallel plates when a spanwise magnetic field is applied. It is found that compared with the purely hydrodynamic case with the Hartmann number Ha=0, the magnetic field has a stabilizing effect on the basic flow for all spanwise wavenumbers β except β=0, and therefore the critical Reynolds number is maintained 5772 regardless of the Hartmann number. Further, we show that the bifurcation of the secondary flow is changed from subcritical to supercritical as Ha is increased, so we deduce the magnetic field has a stabilizing effect on the secondary flow as well as the basic flow.
