WebJun 4, 1998 · However, on the basis of an old calculation by Belinfante [Physica 6, 887 (1939)], it can be shown that the spin may be regarded as an angular momentum generated by a circulating flow of energy in the wave field of the electron. Likewise, the magnetic moment may be regarded as generated by a circulating flow of charge in the wave field. WebDec 19, 2024 · For one, the magnitude of a particular particle's spin is fixed.

Webspin, in physics, the amount of angular momentum associated with a subatomic particle or nucleus and measured in multiples of a unit called the Dirac h, or h -bar (ℏ), equal to the Planck constant divided by 2π. For electrons, neutrons, and protons, the multiple is 0.5; pions have zero spin. WebThe name "spin" derives from an early and quite reasonable explanation for an unusual observation: Quantum particles, such as electrons, behave like miniature magnets. At the time, physicists knew that the motion of electrically charged objects produced north and south magnetic poles. dr berangere canonWebApr 16, 2024 · The half-integer ones, like the spin-1/2 electron, refuse to share the same quantum state, whereas the integer ones, like the spin-1 photon, don't have a problem … dr berchtold stepping hill hospital
