"WebSpin magnetic moment. In physics, mainly quantum mechanics and particle physics, a spin magnetic moment is the magnetic moment caused by the spin of elementary particles. For example, the electron is an elementary spin-1/2 fermion. Quantum electrodynamics gives the most accurate prediction of the anomalous magnetic moment of the electron . " - Spin vector wiki

WebSpin is an angular momentum, so in the rest frame it is a 3-dimensional vector, or 4-dimensional vector with zero time component: v → = ( v 1, v 2, v 3) Each 3D vector can be associated with a 2x2 matrix by the following rule: V = v 3 v 1 − i v 2 v 1 + i v 2 − v 3 In geometry and physics, spinors /spɪnər/ are elements of a complex vector space that can be associated with Euclidean space. Like geometric vectors and more general tensors, spinors transform linearly when the Euclidean space is subjected to a slight (infinitesimal) rotation. Unlike vectors and tensors, a spinor transforms to its negative when the space is continuously rotated through a co…

Spin is described mathematically as a vector for some particles such as photons, and as spinors and bispinors for other particles such as electrons. Spinors and bispinors behave similarly to vectors: they have definite magnitudes and change under rotations; however, they use an unconventional "direction". See more Spin is a conserved quantity carried by elementary particles, and thus by composite particles (hadrons) and atomic nuclei. Spin is one of two types of angular momentum in … See more As the name suggests, spin was originally conceived as the rotation of a particle around some axis.
