WebRelative permeability is the ratio of the permeability of the inductor's core to the permeability of free space. So it depends on the core material. If there is no core material, the relative permeability is 1. With a ferrite core, the … Ferrites are usually ferrimagnetic ceramic compounds derived from iron oxides. Magnetite (Fe3O4) is a famous example. Like most of the other ceramics, ferrites are hard, brittle, and poor conductors of electricity. Many ferrites adopt the spinel structure with the formula AB2O4, where A and B represent various metal cations, usually including iron (Fe). Spinel ferrites usu…
