Sintered Ferrite magnet including"Isotropic" and "Anisotropic" are sintered magnet with either by dry pressed or wet pressed. Tooling is always needed when pressed. The magnetization can be done by axially, radially, multi-poles axially and multi-poles on circumference, etc. Due to the low cost, medium power and productivity by mass production, they are widely used in various industries for many different applications. We can say that the Ferrite magnets were the most popular one magnetic materials for past 30 years.
