Material preparation: Select appropriate magnetic materials, such as iron oxide and cobalt. These materials need to be finely purified and processed to ensure their purity and crystallinity.

Mixing and melting: Mixing magnetic materials with other appropriate additives (such as carbon or titanium) to form the raw material for magnets. These raw materials are usually provided in powder form. Then, heat the raw materials to a high temperature to melt them.

Forging and forming: Pour molten raw materials into pre prepared molds. The shape of the mold determines the shape and size of the final magnet produced. After cooling and solidification in the mold, a preliminary shaped magnet was obtained.

Magnetization: Magnetizing a preliminary shaped magnet. This step can be achieved through various methods, such as using a powerful electromagnetic stone or exposing the magnet to a constant magnetic field. After magnetization, the magnet will gain long-lasting magnetism.

Processing and processing: Processing and processing magnets to achieve the desired shape and performance. This may include machining and surface treatment processes such as cutting, grinding, and polishing.

Quality control: Conduct quality control inspections on the produced magnets. This involves testing and evaluating magnetism, size, and appearance to ensure that the magnet meets the specified standards and requirements.

It should be noted that the preparation process of different types of magnets may vary. For example, samarium cobalt and samarium iron boron materials used for permanent magnets typically require more complex preparation and treatment processes. In addition, the preparation of magnets may also involve additional process steps such as sintering, heat treatment, and coating to meet the requirements of specific applications.
