Abstract
When a liquid metal vessel is placed in a low alternating magnetic field, the bath is submitted to the electromagnetic forces influence. In the low frequency limit, the alternating part of the Lorentz forces becomes predominant. Accordingly, surface waves appear thanks to parametric resonance effects. The aim of this paper is to analyze the mass transfer across an electromagnetically excited liquid-liquid interface. We have developed an electrochemical method which allows the measurement of the instantaneous overall mass transfer. Figs 5, refs 6.
