• Spin (physics) - Wikipedia

    en.wikipedia.org/wiki/Spin_%28physics%29 In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles, composite particles (), and atomic nuclei.. Spin is one of two types of angular momentum in quantum mechanics, the other being orbital angular momentum.The orbital angular momentum operator is the quantum-mechanical counterpart to the classical angular momentum of orbital ...

    simple.wikipedia.org/wiki/Spin_(physics) Spin (physics) Jump to navigation Jump to search. In physics, spin is the constant rotation of an object. For large visible objects like the Earth, spin is the angular momentum of the turning of the Earth around its axis. This tells the amount of rotation that it has.

Unlike regular angular momentum, spin has nothing to do with actual spinning. Normally angular momentum takes the form of an object’s tendency to continue rotating at a particular rate.

    www.britannica.com/science/spin-atomic-physics Spin, 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. The total angular momentum of nuclei more complex than the proton is the vector sum of the orbital ...

Ohanian American Journal of Physics, June 1986, v 54, Issue 6, pp 500-505 Issue Date: June 1986 From the abstract: According to the prevailing belief, the spin of the electron or of some other particle is a mysterious internal angular momentum for which no concrete physical picture is available, and for which there is no classical analog.

Basic Spin Physics 1.1 Magnetism Before talking about magnetic resonance, we need to recount a few basic facts about magnetism. Electromagnetism (EM) is the field of study that deals with magnetic (B) and electric (E) fields, and their interactions with matter. The basic entity that creates electric fields is the electric charge. For

However, that electron cannot occupy the 1s orbital, for it has a property known as spin, which is fundamental to its behaviour. Spin is an intrinsic property of an electron, like its mass or charge. In elementary treatments, spin is often visualized…

One was the closely spaced splitting of the hydrogen spectral lines, called fine structure.The other was the Stern-Gerlach experiment which showed in 1922 that a beam of silver atoms directed through an inhomogeneous magnetic field would be forced into two beams.
