Ferromagnetism - Wikipedia
网页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 | Definition, Cause, Examples, Uses, & Facts
网页2024年8月7日 · 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: Definition, Properties, Examples, and Applications
网页2023年9月15日 · 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.
Ferromagnetism - HyperPhysics
网页Iron, nickel, cobalt and some of the rare earths (gadolinium, dysprosium) exhibit a unique magnetic behavior which is called ferromagnetism because iron (ferrum in Latin) is the most common and most dramatic example. Samarium and neodymium in alloys with cobalt have been used to fabricate very strong rare-earth magnets.

网页2024年8月5日 · A ferromagnetic substance contains permanent atomic magnetic dipoles that are spontaneously oriented parallel to one another even in the absence of an external field. The magnetic repulsion between two dipoles aligned side by side with their moments in the same direction makes it difficult to understand the phenomenon of ferromagnetism.

Ferromagnetism - Engineering LibreTexts
网页Ferromagnetic materials has uniform electron spins pointing in the same direction, while paramagnets have spins in all directions. This causes the ferromagnets to have strong attractive or repulsive forces when introduces to a permanent magnet. On the other hand ferromagnets have weak attractions to strong permanent magnets.
Ferromagnetism - an overview | ScienceDirect Topics
网页Ferromagnetism is the basic method in which a compound forms a permanent magnet or is attracted to a magnetic field. In a nonmagnetic compound, permanent magnetic dipoles tend to line up antiparallel in order to cancel each other out. In ferromagnetism, however, the opposite is true.
