Ferromagnetic materials. Wikimedia Commons has media related to Ferromagnetic materials. This page is a list of substances which exhibit ferromagnetism in the broad sense that includes ferrimagnetism. Some of these are elemental metals, while others are alloys, oxides or other chemical compounds .
Ferromagnetism is a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, steel, nickel, cobalt, etc. and attracts or repels other magnets. A permanent magnet is an object made from a material ...
A magnetic alloy is a combination of various metals from the periodic table such as ferrite that exhibits magnetic properties such as ferromagnetism. Typically the alloy contains one of the three main magnetic elements (which appear on the Bethe-Slater curve): iron (Fe), nickel (Ni), or cobalt (Co). However, alloys such as Heusler alloys ...
Magnetism is the class of physical attributes that occur through a magnetic field, which allows objects to attract or repel each other. Because both electric currents and magnetic moments of elementary particles give rise to a magnetic field, magnetism is one of two aspects of electromagnetism. The most familiar effects occur in ferromagnetic ...
Magnetic susceptibility is a dimensionless proportionality constant that indicates the degree of magnetization of a material in response to an applied magnetic field. A related term is magnetizability, the proportion between magnetic moment and magnetic flux density. [3] A closely related parameter is the permeability, which expresses the total ...
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. [1] This can for example occur when the ...
Ferrite (magnet) A stack of ferrite magnets, with magnetic household items stuck to it. A ferrite is one of a family of iron oxide -containing magnetic ceramic materials. They are ferrimagnetic, meaning they are attracted by magnetic fields and can be magnetized to become permanent magnets. Unlike many ferromagnetic materials, most ferrites are ...
