The effects of an axial magnetic field on the flow and heat transfer about a rotating disk have been analyzed. It is found that the presence of the magnetic field significantly decreases the flow velocities; but increases the torque required to maintain steady rotation of the disk. The heat transfer is also decreased by the magnetic field, with greater redutions occurring for low Prandtl number fluids.
