Abstract

The general Fokker-Planck equation is derived, which takes into account two simultaneous diffusion processes: rotation of the magnetic moment of the particle around its crystal axes and rotation of the particle together with its magnetic moment with respect to the liquid. The influence of the joint diffusion on additional (rotational) viscosity arising in the flow of magnetic fluid in the presence of magnetic field is studied.
