Ferrite magnets made of barium ferrite and strontium ferrite are compressed and then heat treated at a high temperature by sintering. They acquire their shape through a magnetic field during compression. As a result the powdered parts take on a geometric alignment in the later direction of magnetisation.
Keeping in the preference direction (anisotropy) considerably improves the remanence. A magnetisation is only possible in the predetermined preference direction. The following standard magnets are magnetised in the preference direction designated by N-S. Water Pump Rotor Hard Ferrite Ring Magnet
Ferrite magnets correspond to any ceramic material in terms of hardness and brittleness and can only be machined with diamond tools. As a ceramic material, hard ferrite magnets are resistant to weathering and to many chemicals such as solvents, alkaline solutions, salts, weak acids, lubricants and harmful gases. Hard ferrites are the most inexpensive and most widely used permanent magnets worldwide. A rise in temperature per 1 °C leads to a reduction in the flux density by 0.2% while the coercivity increases by 0.3% at the same time.
A reduction in temperature increases the flux density and lowers the coercivity by the same amount.
