General Introduction |
Ferrites are usually non-conductive ferromagnetic ceramic compounds derived from iron oxides such as hematite (Fe2O3) or magnetite (Fe3O4) as well as oxides of other metals. In terms of the magnetic properties, the different ferrites are often classified as "soft" or "hard", which refers to their low or high magnetic coercivity. |
Features |
Soft Ferrite has low coercivity, which means the material's magnetization
can easily reverse direction without dissipating much energy (hysteresis losses), while the material's
high resistivity prevents eddy currents in the core, another source of energy loss.
Permanent ferrite magnets are made of Hard Ferrites, which have a higher coercivity and remanence
after magnetization than soft Ferrite. |
