Zusammenfassung:	The present disclosure relates to a method of controlling an electromagnetic stirrer arranged around a submerged entry nozzle, SEN, of a tundish provided with a stopper rod to control throughput of the tundish, the SEN being configured to provide tapping of molten metal from the tundish and the electromagnetic stirrer being configured to generate a rotating magnetic field in the SEN, wherein the method comprises controlling (S1) the electromagnetic stirrer to operate only when a gas flow rate through the stopper rod is in a first range of 1.5 NL/min to 20 NL/min.
