The magnetic core is basically a material with magnetic permeability which helps confine magnetic fields in transformers. The following are the types of materials used for producing magnetic cores for the transformers
As with any other metallic cores the above-mentioned magnetic cores have their own advantages and disadvantages. You can always consult an electrical expert or an electric cable manufacturer to know which of the above magnetic cores will work perfectly for your transformer.

Jan 14 2012nbsp018332Magnetic Material. A magnetic material placed in a magnetic field H has a magnetic induction B measured in teslas T expressed by Equation 8.44 where 0 is the permeability of free space 4215107TmA1 and the magnetisation MmV is the magnetic moment m per unit volume V of the material Oberteuf 1974.
Magnetite also called lodestone or magnetic iron ore iron oxide mineral FeFe 2 O 4 or Fe 3 O 4 that is the chief member of one of the series of the spinel q.v. group.Minerals in this series form black to brownish metallic moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites stony meteorites and high-temperature sulfide veins.
G.W. Heyes in Iron Ore 2015. 22.214.171.124 Sulfur removal. Magnetite ores often contain sulfide minerals including pyrrhotite and pyrite. Most sulfide minerals are nonmagnetic and can be rejected by magnetic separation. Monoclinic pyrrhotite however in contrast to hexagonal pyrrhotite is magnetic and is recovered in magnetic concentrates.

MAGNETIC SEPARATION This is based on differences in magnetic properties of the ore components If the ore particles are magnetic and the non-magnetic material is gaungethis method is used The finely powdered ore is Understanding Iron Ores and Mining of Iron
Magnetite and maghemite form a close-packed cubic lattice with the iron ions located at interstices between the oxygen ions. These materials have a spinel crystal structure. There are two different interstices that the metal ions can occupy tetrahedral sites and octahedral sites. In the cubic structure of both iron oxides one-third of interstices are coordinated with oxygen ions in a tetrahedral structure while two-thirds are bonded in octahedral sites.
Both magnetite and maghemite are ferromagnetic materials with high magnetic moment when subjected to an external magnetic field. This phenomenon occurs because of a spinel structure with two magnetic sublattices. The Mossbauer technique is a useful tool to differentiate between magnetite and maghemite Haddad etal. 2004 Bandhu etal. 2015. Magnetite and maghemite are the most used SPIONs for biomedical applications including antimicrobial therapies.
Soft materials with low magnetic properties such as annealed iron and steel are examples of temporary magnets. They become magnetic in the presence of a strong magnetic field. They also portray low coercivity. You must have seen how paper clips get attached to each other when a permanent magnet is nearby. Every paper clip becomes a temporary .
Unfortunatelly magnetic core producers are not providing suitable data that would ease the comparision between different core material classes iron powder Ferrite etc..
Founded in 1942 our company has grown to become a pioneer in the design and fabrication of magnetic components. Our tape wound toroidal and tape wound cut cores are at the heart of todays most advanced technologies and electronic components containing our transformer cores achieve a near-perfect magnetic circuit.
Materials . All of the Tools or Weapons in Tinkers Construct can be made from a variety of Materials. For the full list of available materials in your version of the game please check the ingame documentation. A book called quotMaterials and Youquot crafted in the following way
Ferrite is a crystalline magnetic material made of iron oxide and other elements. The mixture is processed at a high temperature and formed into a crystalline molecular structure. Unlike others ferrites are ceramic materials with magnetic properties. Ferrites have high magnetic permeability and high electrical resistivity.
High Frequency Magnetic Core Loss Study Mingkai Mu Abstract The core used to build power inductors and transformers are soft magnetic materials. When there is alternating external field the magnetic moments rotate and consume energy which is the core loss. The core loss depends on the AC flux frequency amplitude waveform DC bias and .

Magnetic materials are categorised as magnetically hard or magnetically soft materials. Magnetically soft materials are easily magnetised but the induced magnetism is usually temporary. For example if you rub a permanent magnet along a nail or a screwdriver the nail or screwdriver will become temporarily magnetised and will emit their own .
the first book to selected electrical and magnetic properties of metals. The materials are sorted by a common materials hierarchy and their property values are given in a consistent system of International Standard SI and customary units. The quality of the data and source of the data also are listed to enable the user to assess the data.
