One-Sided Magnet and Plate
Model 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.

MAGNETICS: Permanent magnets with a one-sided flux are used to attach posters and notes to refrigerators and notice boards, but can also be found in advanced physics applications like particle accelerators. Here we see the magnetic field and flux density. |
