The investigation considers a motion of an electrically conducting liquid in a cylindrical volume exposed to simultaneous influence of a travelling and a rotating magnetic field. When calculating the electromagnetic forces acting on the liquid, the limited length of both the liquid volume and the inductors generating the field is considered. The hydrodynamic characteristics are defined by solving the Navier-Stokes equation. Distributions of the angular velocity of rotating liquid and meridional flows are found for different combinations of rotating and travelling magnetic fields as well as the type of motion trajectories of separate liquid particles. The superimposed above magnetic fields have been found to enhance the efficiency of liquid stirring and to prevent the occurrence of segregation and sedimentation phenomena. Figs 7, Refs 6.
