Ferrite (magnet) - Wikipedia

A ferrite is a ceramic material made by mixing and firing large proportions of iron(III) oxide (Fe 2 O 3, rust) blended with small proportions of one or more additional metallic elements, such as barium, manganese, nickel, and zinc They are both electrically non-conductive, meaning that they are insulators, and ferrimagnetic, meaning they can easily be magnetized or attracted to a magnet...
