Why Is Iron the Best Core for an Electromagnet? | Sciencing

An electromagnet is essentially just a battery attached to a coil of wire wrapped around a metal core. The metal most often used for this is iron. In 1820, the Danish physicist Hans Christian Oersted made an important discovery.

Electromagnet - Wikipedia

Electromagnet. A current through the wire creates a magnetic field which is concentrated in the hole in the center of the coil. The wire turns are often wound around a magnetic core made from a ferromagnetic or ferrimagnetic material such as iron; the magnetic core concentrates the magnetic flux and makes a more powerful magnet.

Why is iron used for the core of an electromagnet? - Quora

Iron is a ferromagnetic material, which means that its electron spins will align strongly in the presence of a magnetic field, and then retain their orientation even after the field is removed. Iron in particular aligns very well to magnetic fields, and thus strengthens the field of an electromagnet very strongly.

What is Iron Ore? - WorldAtlas

Description. Iron ore refers to rocks or minerals from which metallic iron is extracted for commercial use. These minerals appear dark grey to rusty red in color, and are usually rich in iron oxides. Iron occurs in these ores in the form of such chemical compounds as hematite, magnetite, siderite, limonite, or geothite.

Why is iron chosen as the material for the core of the ...

Very, very high magnetic permeability is why. Iron has a very high magnetic permeability. This means that in order to get the same magnetic flux as an air core inductor, it can be much, much smaller. That's really what a transformer is -- create magnetic flux, use magnetic flux to induce current on the other coil.
