Influence of processes of Brownian diffusion and magnetophoresis which are followed by phase transition on characteristics of a stationary plane Couette flow of a magnetic fluid in non uniform magnetic field is considered. Conditions of phase transition in magnetic fluid are accepted as a natural restriction of increasing of concentration of particles in non-uniform magnetic field. Profiles of concentration of particles are calculated and dependences of volume magnetic force, and also viscous force from them are established.
