An isolated spherical insulating particulate suspended by an electric field in a flowing plasma is predicted to exhibit an instability that causes it to spin. The instability, which spontaneously breaks the symmetry about the flow direction, arises when the electric dipole moment, caused by asymmetric charging, points opposite to the external electric field. The theoretical instability criterion derived is that the Debye length should exceed approximately the probe radius divided by the Mach number, when the ion flux asymmetry has its intuitive direction and size. The saturated state is then that the particle rotates at a fraction of the ion plasma frequency. However, for the conditions of many experiments, intuition is incorrect, and the direction of charge asymmetry is such as to yield stability.
