Abstract:
We have calculated components of torque and the interaction energy of a small rotating particle with a permanent dipole moment in the case where the rotation axis is perpendicular to the surface and the dipole axis is inclined to it. The retardation effects were taken into account. An important property of this system is its quasistationarity. When the dipole axis coincides with the rotation axis, the particle does not experience damping and may revolve for infinitely long time. When the dipole axis is inclined to the surface, the situation is possible where the particle is repelled off the surface.
