One-Sided Magnet and Plate
Application ID: 213
Permanent magnets with a one-sided flux have many uses. The one-sided flux behavior is obtained by giving the magnet a magnetization that varies in the lateral direction.
This model shows this technique to model a cylindrical one-sided permanent magnet. A special technique to model thin sheets of high permeability material was used to model a thin metal plate next to the magnet. This circumvents the difficulty of volumetric meshing of thin extended structures in 3D.
