The behaviour of needle asymmetric magnetically soft particles in rotating magnetic field both in free volume and in volume restricted by two coaxial cylinders surfaces is considered. The particle transition into magneto-fluidized state and dynamics in the developed magneto-fluidization regime are analyzed. generalized dependences for determination of the average and mostly probable values of the angular and translational velocities as a function of the field induction, the ratio of the particle length to its diameter, particle diameter, their concentration in a working volume and of the inner cylinder diameter are proposed.
