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, Fe 3 O 4) and iron, have the ability to acquire such attractive powers, and they are often called natural ferromagnets.
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. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial ...
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.

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.

网页2022年7月28日 · 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.

网页4 天之前 · Ferromagnetism is a form of magnetic ordering in which the intrinsic magnetic dipole moment, or spin, of electrons on each crystal-lattice site all align in the same direction. It is the ...
Paramagnetic vs Diamagnetic vs Ferromagnetic – Magnetism
网页2022年10月19日 · Diamagnetism, paramagnetism, and ferromagnetism are the three main types of magnetism seen in materials. Other types include antiferromagnetism, ferrimagnetism, superparamagnetism, and metamagnetism. But, understanding the three main types is a good introduction to the concept.

网页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. It is one of the common phenomena that is encountered in life that is responsible for magnetism in magnets.
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.
