Influence of displacement current on magnetic field distribution in ferrite core within kHz–MHz frequency range

Abstract This paper studies the influence of displacement current in ferrite core on the magnetic field distribution. The expressions used to determine the electric and magnetic field are derived first then the displacement current is calculated based on the electric field distribution together with J = j ωe E . It is found that with the increase of frequency the quantity of displacement current increases and imposes more influence on the magnetic field distribution in the ferrite core, thereby producing more pronounced magnetic skin effect.
