Ferrite (ceramic) magnets are essentially composed of oxide materials with barium carbonate or strontium carbonate, manufactured under a powder metallurgical process
The feature of low recoil permeability, along with the high coercive force, makes them highly resistant to demagnetizing fields.

In addition, their relatively low specific density and economical cost are also very attractive to the magnet designers. When designing the ferrite magnets for a particular application, primary consideration should be given to its shape limitation due to the powder metallurgical manufacturing process and the temperature dependence of ferrite materials.

There are two manufacturing process for ferrite magnets: dry process and wet process.
By dry process, can produce isotropic & anisotropic magnets; by wet process, only anisotropic magnets can be produced.

Isotropic ferrite magnets are not oriented and can be magnetized in any direction;

Anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation.
