Фізична природа вихрових струмів та механізми енергетичних втрат

Abstract

The paper considers the physical nature of eddy currents induced in electrically conductive media under the action of time-varying magnetic fields. The main mechanisms of energy losses associated with eddy currents are analyzed, including Joule losses, the skin effect, and hysteresis losses in ferromagnetic materials. Basic physical relations describing current induction and energy dissipation are presented. It is shown that energy losses are an inherent consequence of electromagnetic induction and strongly depend on field frequency, electrical conductivity, and magnetic properties of materials.
