  The deterministic rotation of a ferromagnetic nanoparticle in a fluid is
considered. The heating arising from viscous friction of a nanoparticle driven
by circularly and linearly polarized alternating magnetic fields is
investigated. Since the power loss of such fields depends on the character of
the induced motion of a nanoparticle, all types of particle trajectories are
described in detail. The dependencies of the power loss on the alternating
field parameters are determined. The optimal conditions for obtaining the
maximum heating efficiency are discussed. The effect of heating enhancement by
a static field is analyzed. The results obtained are actual for the description
of heating in the magnetic fluid hyperthermia cancer treatment, when the size
of the particles used is a few tens of nanometers.
