Abstract
The near magnetic field produced by magnetic components may compromise the performance of nearby devices. This paper analyzed the near magnetic field distribution around toroidal inductors. The mechanism of the field’s origination was studied in this article and modeled with the combination of magnetic dipoles and quadrupoles with clear physical meaning. Intuitive conclusions were drawn from the model and verified by simulation and experiments.
