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.

2024年12月27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, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.

What is Ferromagnetism? Ferromagnetism is a physical phenomenon (long-range ordering), in which certain materials like iron strongly attract each other. Ferromagnets occur in rare earth materials and gadolinium.

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.

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.

2025年2月7日 · Magnetism - Ferromagnetism, Domains, Curie Point: A ferromagnetic substance contains permanent atomic magnetic dipoles that are spontaneously oriented parallel to one another even in the absence of an external field.

2022年4月11日 · Ferromagnetism is a physical phenomenon (long-range ordering) in which certain materials, such as iron, are attracted to one another strongly. Rare earth minerals including gadolinium contain ferromagnets.

What are the differences between ferromagnetism and paramagnetism? Explain why and how does ferromagnetism behave above and below the Curie? What is a common application for ferromagnetism materials and why/how does it work?

ferromagnetism, Physical phenomenon in which certain electrically uncharged materials strongly attract others. It is associated with iron, cobalt, nickel, and some alloys or compounds containing these elements.

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 …
