Halbach Array (Halbach permanent magnet) is a type of magnetic structure. In 1979, American scholar Klaus Halbach discovered this special permanent magnet structure during electron acceleration experiments and gradually improved it, eventually forming the so-called "Halbach" magnet. It is an approximate ideal structure in engineering, which uses the arrangement of special magnet units to enhance the field strength in the unit direction, with the goal of generating the strongest magnetic field with the minimum amount of magnets.

The circular Halbeck array is a special shaped magnet structure designed by combining multiple magnets with the same shape but different magnetization directions to form a circular magnet, in order to enhance the uniformity and stability of the working surface or central magnetic field. The permanent magnet motor using Halbach array structure has an air gap magnetic field that is closer to a sine distribution than traditional permanent magnet motors. With the same amount of permanent magnet material used, the air gap magnetic density of Halbach permanent magnet motors is higher and the iron loss is smaller. In addition, Halbach ring arrays are widely used in permanent magnet bearings, magnetic refrigeration equipment, and magnetic resonance equipment.

Neodymium iron boron, as the third-generation rare earth permanent magnet material, has been widely used due to its excellent magnetic properties. However, neodymium iron boron magnets also have disadvantages such as low Curie temperature, high temperature coefficient of coercivity, and poor chemical stability. In addition, the huge consumption of praseodymium, neodymium, dysprosium, and terbium rare earth resources has raised concerns about environmental damage and the sustainability of rare earth resource protection. Therefore, while continuously improving the performance of neodymium iron boron permanent magnet materials, magnetic material practitioners are also actively developing other new types of permanent magnet materials.
