  Stability analysis of paramagnetic prolate and oblate spheroidal particle in
precessing magnetic field is studied. Bifurcation diagram is calculated
analytically in dependence of magnetic field frequency and precession angle.
The direction of particle in synchronous regime is calculated. Rotational
dynamics and mean rotational frequency in asynchronous regime is found.
Obtained theoretical model gives possibility to calculate analytically dynamics
of the particle in limiting case (when motion is periodic). Theoretically
obtained models were compared with experimental results of rod like particle
dynamics in precessing magnetic field. Experimental results are in good
agreement with proposed theory.
