Origin of diamagnetism
Witryna16 maj 2024 · This article tells the story of diamagnetism. One reason for telling it is that the diamagnetic response is the most common response of matter to a magnetic field and yet the explanation, which is fairly subtle, is rarely given with sufficient care in textbooks. Another reason is that it gives one the opportunity

WitrynaParamagnetism is a form of magnetism whereby some materials are weakly attracted by an externally applied magnetic field, and form internal, induced magnetic fields in the direction of the applied magnetic field. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the … Witryna5 lis 2024 · Diamagnetism, to a greater or lesser degree, is a property of all materials and it always makes a weak contribution to the material’s response to a magnetic field. However, for materials that display some other form of magnetism (such as ferromagnetism or paramagnetism), the diamagnetic contribution becomes negligible. ...
WitrynaTwo 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. They were discovered more than 2,000 years ago, and all early scientific studies of magnetism were conducted on these materials.
