One-Sided Magnet and Plate

Application ID: 213


One-sided magnets are magnets designed to have both magnetic poles emerging from the same side of the magnet. This results in the magnetic flux being concentrated on one side of the magnet. These kinds of magnets are found in many applications from the common fridge magnet to particle accelerators. This tutorial demonstrates a method to model a cylindrical one-sided permanent magnet by giving the magnet a magnetization that varies in the lateral direction. The model simulates the magnetic flux from the magnet and its interaction with a nearby thin metal plate.

This model example illustrates applications of this type that would nominally be built using the following products:
