In this paper the steady three-dimensional stagnation-point flow of an incompressible, homogeneous, electrically conducting micropolar fluid over a flat plate is numerically investigated. The fluid is permeated by a uniform external magnetic field H0. The effects of the magnetic field on the velocity and on the microrotation profiles are presented graphically and discussed. The results obtained indicate that the thickness of the boundary layer decreases when the magnetic field increases. Moreover H0 tends to prevent the occurrence of the reverse flow and of the reverse microrotation.
