Abstrakt v dalším jazyce:	Electromagnetic stirring (EMS) is nowadays widely applied in continuous casting of metals, in order to increase the quality of the solidified cast. Therefore, an accurate investigation of the stirring effect represents a matter of great interest. Numerical simulations normally calculate only the average Lorentz force distribution inside the molten metal, which plays the major role in the final velocity field generation. Double-frequency component of the force is then neglected, and the real Lorentz force is approximated. In this paper, the stirring effect under the influence of the real Lorentz force distribution is investigated: both average and double-frequency components are calculated, and the resulting flow field inside the melt is analysed. Numerical simulations are experimentally validated with the use of GaInSn melt and UDV probe.
