  5. Ferrite core - Wikipedia

    en.wikipedia.org/wiki/Ferrite_core

    Several ferrite cores. In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents).

  6. Ferrimagnetism - Wikipedia

    en.wikipedia.org/wiki/Ferrimagnetism

    Ferrite, a ceramic compound, is one of the most common examples of a ferrimagnetic material. A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments , as in antiferromagnetism , but these moments are unequal in magnitude, so a spontaneous magnetization remains. [ 1 ]

  7. Ferrite bead - Wikipedia

    en.wikipedia.org/wiki/Ferrite_bead

    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. Ferrite beads employ high-frequency current dissipation in a ferrite ceramic to build high-frequency noise suppression devices.

  8. Magnetic core - Wikipedia

    en.wikipedia.org/wiki/Magnetic_core

    A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical, electromechanical and magnetic devices such as electromagnets, transformers, electric motors, generators, inductors, loudspeakers, magnetic recording heads, and magnetic assemblies.
