Abstract
Turbulent flow of conducting melts under the action of a rotating magnetic field (RMF), synchronously amplitude-modulated in a special way, is theoretically described in the induction-free approximation using the ``external'' friction model. Analytical expressions describing the magnetic field, current density, electromagnetic body forces and velocity field in the melt are presented. Figs 3, Refs 3.
