Magnet Manufacturing Process How Are Magnets

Magnet Manufacturing Process. There are several processes for making magnets, but the most common method is called Powder Metallurgy. In this process, a suitable composition is pulverized into fine powder, compacted and heated to cause densification via “liquid phase sintering”. Therefore, these magnets are most often called sintered magnets.

Magnet Powder magnets Britannica

Magnet Magnet Powder magnets: The problem of producing magnets composed of compacted powders is essentially that of controlling particle sizes so that they are small enough to comprise a single domain and yet not so small as to lose their ferromagnetic properties altogether. The advantage of such magnets is that they can readily be molded and machined into desired shapes.
