Ceramic or also known as hard ferrite material are made from raw

Ceramic or also known as hard ferrite material are made from raw materials of strontium carbonate and iron oxide. They are nonstrategic, readily available and low in cost. As a result, the use of ceramic magnets in most applications is more economical than other materials. Irreversible changes can result from very low temperatures, and the magnetic qualitities can be restored only by re-magnetization. Irreversible changes can be avoided by providing adequate magnetic length, that is permeance coefficieint.
