Starting from a continuum constituted by charged tops, we formulate theclassical counterpart of a previously obtained covariant continuity-likeequation for the spin current. Such a formulism provides an intuitive pictureto elucidate the non-conservation of the spin current and to interpret thecondition for the emergence of an infinite spin relaxation time. It alsofacilitates the discussion on the spin precession in a one-dimensional quantumwire with Dresselhaus and Rashba spin-orbit couplings. Furthermore, we derivethe diffusion equations for both the charge and spin densities and find thatthey couple to each other due to the Zitterbewegung.
