Frequency dependence of an alternating magnetic field driven flow
Cramer, A.; Galindo, V.; Zennaro, M.;
The flow induced by a single-phase alternating magnetic field (AMF) is studied mainly numerically, and by two preliminary experiments of quite different size. For validation, the well known dependence of the characteristic velocity on magnetic induction is reproduced experimentally and in the simulations. It is shown that the flow structure depends drastically on the frequency of the AMF. An investigation of the change of the characteristic velocity with frequency results in a quantitative difference of flows in an AMF compared to rotating and travelling magnetic fields.
