Various ferrite cores used to make small transformers and inductors A ferrite AM loopstick antenna in a portable radio, consisting of a wire wound around a ferrite core A variety of small ferrite core inductors and transformers. Ferrites that are used in transformer or electromagnetic cores contain nickel, zinc, and/or manganese [20] compounds ...
Ferrites that are 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 .
A ferrite bead at the end of a Mini USB cable. A ferrite bead – also called a ferrite block, ferrite core, ferrite ring, EMI filter, or ferrite choke [1] [2] – is a type of choke that suppresses high-frequency electronic noise in electronic circuits.
Junction circulators use permanent magnets to provide the static magnetic bias for the ferrite(s). However, switching circulators typically rely on the remanent magnetization of the ferrite itself. The ferrites that are used in switching circulators have square magnetic hysteresis loops and often sub-Oersted coercivities. Such a ferrite ...
Barium Ferrite is used in tape drives and floppy disks. Barium ferrite is used in recording media, permanent magnets, and magnetic stripe cards (credit cards, hotel keys, ID cards). Due to the stability of the material, it is able to be greatly reduced in size, making the packing density much greater.

This directional property is used in the construction of microwave devices like isolators, circulators, and gyrators. Ferrimagnetic materials are also used to produce optical isolators and circulators. Ferrimagnetic minerals in various rock types are used to study ancient geomagnetic properties of Earth and other planets.
Zinc ferrites are a series of synthetic inorganic compounds of zinc and iron with the general formula of Zn x Fe 3−x O 4. Zinc ferrite compounds can be prepared by aging solutions of Zn(NO 3 ) 2 , Fe(NO 3 ) 3 , and triethanolamine in the presence and in the absence of hydrazine , [ 1 ] or reacting iron oxides and zinc oxide at high temperature.
