The device comprises a coil around a core of a material with high permeability, with a gap surrounded on two sides by capacitor planes. In the device, by feed with AC voltage at very high frequency is generated partly an electric current which flows through material placed in the gap, partly a magnetic flow which flows through the material at right angles to the current, and which pulsates at the same frequency as the current. The current and the nmagnetic flow produce a force which pulsates at double the frequency, and which acts at right-angles to both the current and the magnetic flow. |
