The effects of thermal radiation on tlow past an impulsively started semi-infinite vertical plate in the presence of magnetic field have been studied. The fluid considered is a gray, absorbing-emitting radiation but nonscattering medium. The dimensionless governing equations are solved by an efficient, more accurate, unconditionaIly stable and fast converging implicit scheme. The effects of velocity and temperature for different parameters like thermal radiation, magnetic field, Schmidt number, thermal Grashof number and mass Grashof number are studied. It is observed that the velocity decreases in the presence of thermal radiation or magnetic field.
