摘要：
Magnetic components are generally used in electrical devices. However the interference to the environment of these components is not widely explored. This study presents a comparative analysis of the magnetic field distribution of three different winding techniques with a toroidal core. The analytical model is based on finite element analysis. The effects of the winding layout around a single core and double core are discussed. It is found out the winding techniques make some contribution to the radiated field. Moreover, this paper studied the near field coupling of a core when a high conductivity shield placed in the vicinity. The side without the source is immune, but the magnitude of field in the side with the source is up.
