Abstract
This paper deals with numerical and experimental investigation of the liquid metal flow inside a cylindrical crucible exposed to MHD stirring generated by modulated travelling and rotating magnetic fields. It has been found that in a discontinuous alternate mode, when the liquid metal in the crucible is subjected to a travelling magnetic field at one time interval and to a rotating magnetic field at another interval, the flow becomes more axially symmetric compared to a flow excited by the simultaneous and continuous action of both magnetic fields.
