Effect of an axially applied magnetic field on
the stability of a ferrofluid flow in an annular space between two coaxially
rotating cylinders with nonaxisymmetric disturbances has been
investigated numerically. The critical value of the ratio
of angular speeds of the two cylinders, at the onset of the first
nonaxisymmetric mode of disturbance, has been observed to be
affected by the applied magnetic field.
