We consider a spherical particle rotating near a plane electrode in a uniform electric field. The effect of the electrode is considered using the method of images. We analytically calculate the electric torque on the particle and formulate the equations describing the evolution of the rotation rate and the electric multipoles. We investigate the colloid dynamics numerically by solving the full set of evolution equations and analytically by means of asymptotic solutions for large separations from the boundary.
