The metals iron, cobalt and nickel, and certain alloys are vastly more magnetic than any other known substance; these metals are said to be ferromagnetic. They possess magnetic properties in the absence of a magnetic field.

It is a term for greatly attracted to magnetic fields.

With the property of ferromagnetism. Iron, cobalt, and nickel are ferromagnetic metals.

Greatly attracted to magnetic fields. Ferromagnetism is the magnetic property in certain materials that causes them to be attracted to magnetic fields.

Hysteretic material the permeability of which depends on the magnitude of an applied magnetizing force.

A term meaning magnetic properties of iron. A material does not have to have iron in it to be ferromagnetic, such as most ferrites. The main property of a ferromagnetic material is its strong affinity for concentrating and magnifying a magnetic field formed by electric current flow into magnetic flux.

a substance, such as iron, that has a large positive magnetic susceptibility.

The presence of metallic iron or of the divalent ion Fe2+ that possesses magnetism.

The ability to become highly magnetic and have the ability to retain a permanent magnetic moment. The elementary magnetic dipoles inside the domain are all oriented in a direction parallel to each other.
