生产金属和合金、铁和有色金属连续铸锭和铸件的工艺过程的效率主要取决于液相的传热传质强度。energetics Technologies Ltd （ET）开发并提出的电磁搅拌（EMS）方法为控制这种传热传质提供了可能。它使用由电流系统激发的非谐波行进（旋转）磁场，电流系统的幅值和频率由周期（及时）函数调制，其频率超过载流子频率。具有合适的调制参数选择
The efficiency of technological processes of producing metals and alloys, continuous ingots and castings of ferrous and non-ferrous metals is mainly determined by the intensity of heat and mass transfer in the liquid phase. The Electromagnetic stirring (EMS) method developed and proposed by En-ergetics Technologies Ltd (ET) provides a possibility of controlling such heat and mass transfer. It uses anharmonic traveling (rotating) magnetic fields excited by a system of electric currents whose amplitude and frequency are modulated by periodic (in time) functions with the frequency exceeding the carrier frequency. With a suitable choice of modulation parameters
