This is a rod magnet with a diameter of 4mm and a thickness of 5mm. The material is sintered ferrite, which belongs to a type of permanent magnet. This magnetic material not only has strong demagnetization resistance, but also has the advantage of low cost. It has a wide range of applications, from motors, sensors, speakers to toys, handicrafts, and is currently the most widely used permanent magnet material.

Ferrites are divided into two types: isotropic and anisotropic. Isotropic magnets, due to their lack of orientation, can be magnetized in any direction, while anisotropic magnets, due to their orientation in the manufacturing direction, need to be magnetized in the chosen direction. Heterogeneous magnetism is stronger than isotropic magnetism.
