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 ...
A branch of physics that studies atoms as isolated systems of electrons and an atomic nucleus. Compare nuclear physics. atomic structure atomic weight (A) The sum total of protons (or electrons) and neutrons within an atom. audio frequency A periodic vibration whose frequency is in the band audible to the average human, the human hearing range.
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.

Other names include "loopstick antenna", "ferrod", and "ferrite-rod antenna". "Ferroceptor" [7] is an older alternative name for a ferrite rod aerial, mainly used by Philips where the ferrite core would be called a "Ferroxcube" rod (a brand name acquired by Yageo from Philips in the year 2000). The short terms "ferrite rod" or "loop-stick ...
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.
Meaning SI unit of measure alpha: alpha particle: angular acceleration: radian per second squared (rad/s 2) fine-structure constant: unitless beta: velocity in terms of the speed of light c: unitless beta particle: gamma: Lorentz factor: unitless photon: gamma ray: shear strain: radian
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.
Ferrite may refer to: Ferrite (iron) , one of the allotropes of iron that is stable at room temperature and pressure, α-Fe Ferrite (magnet) , a ferromagnetic ceramic material
