The magnetization process for axially multipole magnetized magnets involves specialized magnetizing fixtures that generate a controlled magnetic field along the thickness. In single-plane types, this process creates alternating poles on one surface, while in double-plane types, it produces multiple axially magnetized sections with alternating North (N) and South (S) poles across both surfaces. The double-plane axially multipole magnetizing fixture is typically achieved by combining a pair of single-plane axially multipole magnetizing fixtures.

Axially multipole magnetized magnets, with their ability to produce alternating magnetic poles along the thickness, are utilized across a variety of industries and applications. Their versatility comes from the range of available shapes—such as disc, ring, rectangular, and flexible sheet forms—across materials like Neodymium magnets and bonded magnets.
Rubber magnets, also known as flexible magnets, have lower magnetic strength compared to other magnet types. However, their holding force—crucial in their most common applications—can be enhanced by applying single-plane multipole magnetization. This one-sided magnetization, sometimes referred to as Halbach magnetization, concentrates magnetic strength on one side. Rubber magnets with high-precision axially multipole magnetization are also used as encoder magnets, where alternating magnetic poles are critical for accurate position sensing.
Injection ferrite magnets with axially multipole magnetization are typically produced in ring forms and are widely used in sensing applications. Beyond standard rings, they can also be manufactured in special shapes with varied magnetization patterns, while maintaining the axially multipole structure to meet the specific requirements of these applications.
The most commonly used bonded magnets, including compression molded and injection molded magnets, are generally applied in sensing, holding, and coupling areas when magnetized in axially multipole configurations. These magnets are typically produced in ring shapes and are used in both single-plane and double-plane types.
Neodymium magnets are available in ring, disc, and rectangular shapes and are generally magnetized as double-plane multipole magnets. They are commonly used in holding applications, permanent magnet motors, and certain coupling devices.
In magnetic nozzles of hair dryers, the limited space available for ring magnets necessitates the use of bonded magnets. Although bonded magnets have lower magnetic properties compared to Neodymium magnets, axially multipole magnetization is applied to enhance the holding force between the magnets and their ferromagnetic counterparts, ensuring secure and efficient functionality.
