Ferrite (magnet) For other uses, see Ferrite (disambiguation). A ferrite is a type of ceramic compound composed of iron(III) oxide (Fe2O3) combined chemically with one or more additional metallic elements. They are both electrically nonconductive and ferrimagnetic, meaning they can be magnetized or attracted to a magnet.

Ferrimagnetism In physics, a ferrimagnetic material is one that has populations of atoms with opposing magnetic moments, as in antiferromagnetism; however, in ferrimagnetic materials, the opposing moments are unequal and a spontaneous magnetization remains. This happens when the populations consist of different materials or ions. Ferrimagnetism is exhibited by ferrites and magnetic garnets. The oldest known magnetic substance, magnetite, is a ferrimagnet; it was originally classified as a ferromagnet ...

Magnetite Magnetite is a mineral, one of the three common naturally occurring iron oxides (chemical formula Fe3O4) and a member of the spinel group. Magnetite is the most magnetic of all the naturally occurring minerals on Earth.Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of iron, and this was how ancient people first noticed the property of magnetism.mall grains of magnetite occur in almost all igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide.

The Compass and other Magnetic Innovations Ferrites were first discovered thousands of year ago. Large deposits were found in the district of Magnesia in Asia Minor, which is how mineral got the name of magnetite (Fe3O4). Magnetite was nicknamed lodestone and used by early navigators to locate the magnetic North Pole.

How to define Ferrite in CST? First, define the electric and magnetic properties of the Ferrite. For example, permittivity, electric loss tangent, permeability, magnetic loss tangent,... Second, create a new material in CST and then insert all those properties values. Finally, add the created material to CST library.

What Elements Are Magnetic? Powerful rare earth magnets are referred to by the names of their component rare earth elements, but these elements are not ferromagnetic on their own. Neodymium magnets are the best-known type of rare earth magnets and composed of an alloy of neodymium, iron and boron. Samarium magnets consist of an alloy of samarium and cobalt. These are useful at high temperatures where neodymium magnets would lose their ferromagnetism.

Iron (II) hydroxide The natural analogue of iron(II) hydroxide compound is a very rare mineral amakinite, (Fe,Mg)(OH) 2. Reactions. Under anaerobic conditions, the iron(II) hydroxide can be oxidized by the protons of water to form magnetite (iron(II,III) oxide) and molecular hydrogen. This process is described by the Schikorr reaction: 3 Fe(OH) 2 → Fe 3 O 4 + H 2 + 2 H 2 O. Anions such as selenite and selenate can be easily adsorbed on the positively charged surface of iron(II) hydroxide, where they are ...

Magnetite A complex pattern of electrons between the two forms of iron is the source of its magnetic nature. Although other metallic minerals may mimic magnetite’s color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence.

Ferrite Cores Ferrite Cores Custom, cost-effective solutions to fit your needs. Ferrites are ceramic, homogeneous materials composed of various oxides with iron oxide as their main constituent. Based upon chemical composition, soft ferrites are divided into: manganese-zinc ferrite and nickel-zinc ferrite. In each category many different MnZn and NiZn material grades can be manufactured by changing the chemical composition or manufacturing technology.

Ferrite core 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. Because of their comparatively low losses at high frequencies, they are extensively used in the cores of RF transformers and inductors in applications such as switched-mode power supplies, and ferrite loopstick antennas

How to define Ferrite in CST? For designing an isolator you must use an anisotropic ferrite, which is called gyrotropic in CST. The ferrite must be biased by a static magnetic field in the correct orientation. You must get the dielectric and magnetic properties for the ferrite from the manufacturer.

Magnetite Lodestones were used as an early form of magnetic compass. Magnetite typically carries the dominant magnetic signature in rocks, and so it has been a critical tool in paleomagnetism, a science important in understanding plate tectonics and as historic data for magnetohydrodynamics and other scientific fields.mall grains of magnetite occur in almost all igneous and metamorphic rocks. Magnetite is black or brownish-black with a metallic luster, has a Mohs hardness of 5–6 and a black streak. The chemical IUPAC name is iron(II,III) oxide and the common chemical name is ferrous-ferric oxide.

Ferrite (magnet) Early computer memories stored data in the residual magnetic fields of hard ferrite cores, which were assembled into arrays of core memory. Ferrite powders are used in the coatings of magnetic recording tapes. One such type of material is iron (III) oxide. Ferrite particles are also used as a component of radar-absorbing materials or coatings used in stealth aircraft and in the absorption tiles lining the rooms used for electromagnetic compatibility measurements.

Ferromagnetism Ferromagnetism is the basic mechanism by which certain materials form permanent magnets, or are attracted to magnets. In physics, several different types of magnetism are distinguished. Ferromagnetism is the strongest type: it is the only one that typically creates forces strong enough to be felt, and is responsible for the common phenomena of magnetism in magnets encountered in everyday life. Substances respond weakly to magnetic fields with three other types of magnetism, paramagnetism, diamag
