A traveling magnetic field (TMF) is attractive for melt crystal growth as it offers a direct flow driving mechanism. We present numerical and experimental results on the TMF driven flow in an isothermal model fluid. The TMF is generated by a system of six equidistant coils, which are fed by a thme phase current power supply to create an up- or downward directed traveling field. Special attention is focused on the description of the electromagnetic fields for varying field frequency, and its influence on the resulting melt velocity. (c) 2006 Elsevier B.V. All rights reserved.
