That is, the electron is like a small bar magnet! As a bar magnet, it would possess a magnetic dipole moment, and would thus be deflected by the non-uniform magnetic field because of the force we derived earlier. Webb5 mars 2024 · A proper account of the mechanism at the atomic level of the cause of diamagnetism requires a quantum mechanical treatment, but we can understand the phenomenon qualitatively classically. We just have to think of an atom as being a nucleus surrounded by electrons moving in orbits around the nucleus. lands lawn care

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 hemlock\u0027s d2
