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.

— Ferromagnetism: Ferromagnetic materials are strongly attracted to magnets and can become magnetized. Above a temperature called the Curie point, ferromagnetic materials lose their magnetism. Iron, cobalt, nickel, most of their alloys, and some rare earth metal compounds are ferromagnetic.

— Ferromagnetism, physical phenomenon in which certain electrically uncharged materials strongly attract others. Two materials found in nature, lodestone (or magnetite, an oxide of iron, Fe3O4) and iron, have the ability to acquire such attractive powers, and they are often called natural.

— Ferromagnetism is an exciting phenomenon observed in certain materials, known as ferromagnetic materials, that can retain their magnetization even after removing an external magnetic field. Ferromagnetic materials can become ferromagnets and interact strongly with other magnets and magnetic fields.

— For example, Fe, Co, Ni, Nd 2 Fe 14 B, SmCo 5, and YCo 5 are all ferromagnets, Cr and MnO are antiferromagnets, and Fe 3 O 4 and CoFe 2 O 4 are ferrimagnets. Diamagnetic compounds have a weak negative susceptibility (χ < 0). Definitions. H = applied magnetic field (units: Henry (H)) B = induced magnetic field in a …

Most metals with magnetic properties are ferrous: metals and alloys that contain iron. These ferrous metals include mild steel, carbon steel, stainless steel, cast iron, and wrought iron. Their high carbon content leads to being prone to rust (with the exception of stainless steel and wrought iron), but their tensile strength and durability ...

— In reality, all materials are magnetic–they just don't stick to magnets. I gave you a list of ferromagnetic elements (and ferrimagnetic compounds) which do stick to magnets, but in certain cases, even metals that do not normally stick to magnets can be affected by a magnetic field.

There are many artificial alloys and ceramic materials which are ferromagnetic. As with paramagnetic materials, the atoms have permanent magnetic moments, but with the difference that these moments are not randomly oriented but are strongly aligned to the crystallographic axes.

— The most common ferromagnetic materials are cobalt, iron, nickel, along with Lodestone a naturally magnetized mineral and other rare earth metal compounds. A common usages of ferromagnetic materials affecting our everyday lives is through magnetic storage in the form of data.
