Isotropic ferrite magnets

1. Raw materials: The process of making magnets begins with the raw materials. The most commonly used materials for making magnets are iron, nickel, cobalt, and their alloys.

2. Melting: The raw materials are melted in a furnace at a high temperature. The molten metal is then poured into a mold to form the desired shape.

3. Cooling: The molten metal is allowed to cool and solidify in the mold. The cooling process is carefully controlled to ensure that the metal solidifies in a uniform manner.

4. Annealing: After the metal has solidified, it is annealed to improve its magnetic properties. Annealing involves heating the metal to a high temperature and then slowly cooling it down.

5. Machining: The annealed metal is then machined to the desired shape and size. This process involves cutting, drilling, and grinding the metal to achieve the desired shape and surface finish.

6. Magnetization: The final step in the process is magnetization. The magnet is placed in a magnetic field and exposed to a strong magnetic field. This aligns the magnetic domains in the metal and creates a permanent magnet.

7. Quality control: Throughout the process, quality control checks are carried out to ensure that the final product meets the required specifications. These checks include measuring the magnetic properties of the magnet, checking the dimensions and surface finish, and testing the strength of the magnet.
