From https://en.wikipedia.org/wiki/Spin_(physics) https://en.wikipedia.org/wiki/Spin_(physics): >In quantum mechanics and particle physics, spin is an intrinsic form of angular momentum carried by elementary particles And >In some ways, spin is like a vector quantity; it has a definite magnitude, and it has a "direction" (but quantization makes this "direction" different from the direction of an ordinary vector).
