Ferrite Core. A ferrite core is a kind of magnetic core, which is made up of ferrite. On ferrite cores the windings of switching transformers and other types of wound components like inductors are made. It is used because of its properties of high magnetic permeability, which is coupled with low electrical conductivity.
