Application of magnetically driven tornado-like vortex for stirring floating particles into liquid metal

A tornado-like vortex is driven by magnetic body forces. A continuously applied rotating magnetic field provides source of the angular momentum. A pulse of a much stronger travelling magnetic field drives a converging flow that temporarily focuses this angular momentum towards the axis of the container. A highly concentrated vortex forms that produces a funnel-shaped surface depression. The ability of this vortex to entrain floating unwetted particles in liquid metal is investigated experimentally.
