EN The paper presents and discusses the results of research aimed at developing the optimal System for Generation of the fast-changing Rotating Magnetic Field (SGRMF) that causes the hyperthermic effect in magnetic liquids. In the calculations and design of the SGRMF, the three-dimensional (3D), original approach of the Finite Element Method (FEM) has been used. The FEM software prepared by the authors is based on the Ω-T0 formulation with nodal values of the scalar potential Ω to describe the magnetic field, and edge values of the electric vector potential T0 to define currents in windings. In the prepared model of the SGRMF, the relations describing the conversion of electromagnetic energy into thermal energy in magnetic fluids have been taken into consideration. The results of the proposed FEM model and elaborated software are presented and compared with the results obtained from the measurements on the specialized test stand. The prototype of the SGRMF system has been designed and built. Finally, the application of this prototype in the investigations of the hyper-thermal effect in a selected magnetic fluid of APG 513 type is given and discussed.
