Ferromagnetism

Many substances are found to be magnetic, in that they are attracted by magnetic and electric fields, but it is found that the metals iron, cobalt, nickel and a number of alloys posses a greater level of magnetism than other substances. This powerful magnetism is called ferromagnetism, and is due to a large magnetic moment in the atoms of the metals due to an unbalanced spin of the electrons in their inner orbits. ...

ferromagnetism

ferromagnetic. Compare with paramagnetic and diamagnetic. Ferromagnetic materials exhibit magnetism even in the absence of an external magnetic field. Ferromagnetic materials contain regions where many paramagnetic atoms or ions have magnetic moments that are aligned in the same direction. Iron, cobalt, nickel, and gadolinium are elements that can ...

ferromagnetism

Ferromagnetism is a type of magnetism in which the magnetic moments of atoms in a solid are aligned within domains which can in turn be aligned with each other by a weak magnetic field. The total magnetic moment of a sample of the substance is the vector sum of the magnetic moments of the component domains. In an unmagnetized piece of ferromagnetic...

ferromagnetism

Form of magnetism that can be acquired in an external magnetic field and usually retained in its absence, so that ferromagnetic materials are used to make permanent magnets. A ferromagnetic material may therefore be said to have a high magnetic permeability and susceptibility (which depends upon temperature). Examples are iron, cobalt, nickel, and ...

Ferromagnetism

Ferromagnetism is the basic mechanism by which certain materials (such as iron) form permanent magnets, or are attracted to magnets. In physics, several different types of magnetism are distinguished. Ferromagnetism (including ferrimagnetism) is the strongest type; it is the only type that creates forces strong enough to be felt, and is responsibl...
