Isotropic ferrite magnets

What is the isotropic and the anisotropy of ferrite magnets?

Ferrite permanent magnets are divided into two types: isotropic and anisotropic. The manufacturing methods include dry press molding and wet press molding. Because the raw materials are cheap and mass production is easy, it is the most demanded and most versatile material on the market....
