The short terms "ferrite rod" or "loop-stick" sometimes refer to the coil-plus-ferrite combination that takes the place of both an external antenna and the radio's first tuned circuit or just the ferrite core itself (the cylindrical rod or flat ferrite slab). These broadcast ferrite rod aerials nearly always have a permeability of 125. [8]
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.
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 ...
Core relies on the square hysteresis loop properties of the ferrite material used to make the toroids. An electric current in a wire that passes through a core creates a magnetic field. Only a magnetic field greater than a certain intensity ("select") can cause the core to change its magnetic polarity.

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.
Small toroidal inductors with ferrite core Traditional transformers wound on rectangular-shaped cores. Interior of a linear power supply with toroidal mains transformer. Toroidal inductors and transformers are inductors and transformers which use magnetic cores with a toroidal (ring or donut) shape.
Chokes for even higher frequencies have non-magnetic cores and low inductance. A modern form of choke used for eliminating digital RF noise from lines is the ferrite bead, a cylindrical or torus-shaped core of ferrite slipped over a wire. These are often seen on computer cables.
