New methods for a fast and easy computation of stray fields created by wound rods

摘要

A quick and easy computation involving magnetic rods is presented. Rods are replaced by different kinds of distributions (magnetization, magnetic charges) calculated by collocation. These distributions can be punctual or surfacic (disc) in the rod according to the density of the mesh used. Then, three-dimensional geometries can be quickly and easily modeled instead of using uneasy finite-element methods.
