Analysis of Electromagnetic Characteristics of Magnetohydrodynamic Rotator for Liquid Metals

There has been set and analytically solved task on calculation of the electromagnetic field in the area of the "cylindric inductor - channel with liquid metal" system. The inductor part includes a polyphase winding with electric current that enables generating the rotating magnetic field. The solution for electromagnetic field vector has been found in the Fourier series of a complex form using Bessel functions. The task was solved in a 2D design using the cylindrical coordinate system. There have been obtained the relations of the current density in the channel metal, electromagnetic power and moment to the parameters and modes of system operation. The electromagnetic rotator for the liquid metal can be used to introduce fine metal particles (chips, sawdust) into the reverberatory melting furnace.
