What is a Ferrite Core?

*Ferrite core is a type of magnetic core made of ferrite on which the windings of electrical transformers and other wound components such as inductors are formed. Ferrite cores are used because of their properties of high magnetic permeability combined with low electrical conductivity. Due to their relatively low losses at high frequencies, they are also widely used in the cores of RF transformers and inductors such as switched-mode power supplies and ferrite loopstick antennas for AM radio receivers.

Ferrites are ceramic compounds of the transition metals with oxygen, which are ferrimagnetic but non-conductive. Ferrites used in transformer or electromagnetic cores contain iron oxides combined with nickel, zinc and/or manganese compounds. They have a low coercivity and are called "soft ferrites" to distinguish them from "hard ferrites", which have a high coercivity and are used to make ferrite magnets. The low coercivity means that the magnetization of the material can easily change direction while dissipating very little energy (hysteresis losses). At the same time, the high resistivity of the material prevents eddy currents in the core, another source of energy loss.
