Analysis of the skin effect on the coil with high frequency current source

The electromagnetic theory is applicated on the field of electromagnetic continuous casting(EMC). This paper treats the stream phenomena of high frequency current on the solid-loop coil of which consists the hollow conductor. The governing equation is derived from elctromagnetic field theory and the characteristics are analyzed by FEM. The results may be availabe data on designing the optimum shape of the coil for the improved pinch effect.
