Characteristics of Ferrite Magnets
This section provides information of the physical properties of Ferrite Permanent Magnets.
Ferrite permanent magnets have good machining properties which allows them to be cut into different shapes and sizes - they are cut with diamond tooling; standard drills and wire spark erosion techniques do not work (they are electrically insulating so current does not pass through them due to their extremely high electrical resistance, hence their other name of Ceramic Magnets).

Ferrite magnets are made by wet or dry pressing and sometimes by extrusion. Wet pressing gives stronger magnetic properties (e.g. Ferrite C8). Dry pressing gives improved dimensional tolerances (e.g. Ferrite C5). The magnets are then sintered to fuse the powder together and are then machined to final shape. The extrusion method can be applied to produce arc segment shapes which are then cut to length. Sometimes new tooling is required to produce the ferrite magnets if existing tooling does not allow the shape to be produced. Typical tolerances for ferrite magnets are +/-0.25mm although +/-3% is also used.
