In modern industry and technology, the design and magnetization direction of magnets play a decisive role in their performance and applications. diametrically magnetized circular magnets, as a type of permanent magnet with a special magnetization method, have their magnetization direction aligned along the diameter of the disk rather than the traditional axial (thickness) direction. This unique magnetization method enables them to generate radial magnetic field, offering unparalleled advantages in applications such as sensors, motors, and magnetic transmission systems.

Characteristics of diameter-magnetized circular magnets:

The two magnetic poles are located at both ends of the disc diameter, forming a unique magnetic field distribution, as shown in the figure below.

The magnetic field is strongest at both ends of the diameter and weaker in the center area, with an arc-shaped magnetic field distribution suitable for specific application scenarios.
