Abstract The deterministic spherical motion of the ferromagnetic fine particle with frozen magnetic moment is considered. The energy absorbed from circularly polarized field is transformed into thermal energy through the viscous friction between fine particle and carrier fluid. Using the classical equations of motion, the mode of uniform precession and the mode of torsional oscillation are described analytically in overdamped limit. The corresponding relationships for the power loss are obtained. Critical influence of the static field on the power loss value is discussed.
