  The formula for dipole radiation reaction torque acting on a system of
charges, and the Larmor-like formula for the angular momentum loss by this
system, differ in the time derivative term which is the analogue of the Schott
term in the energy loss problem. In the well-known textbooks this discrepancy
is commonly avoided via neglect of the Schott term, and the Larmor-like formula
is preferred. In the present paper both formulae are used to derive two
different equations of motion of a polarized spinning-top. Both equations are
integrable for the symmetric top and lead to quite different solutions. That
one following from the Larmor-like formula is physically unplausible, in
contrast to another one. This result is accorded with the reinterpretation of
Larmor's formula discussed recently in the pedagogical literature. It is
appeared, besides, that the Schott term is of not only academic significance,
but it may determine the behavior of polarized micro- and nanoparticles in
nature or future experiments.
