Electron Spin

Electron spin is a fundamental property of electrons, describing their intrinsic angular momentum—a kind of tiny, inherent rotation. Although not a literal spinning motion like a planet, it influences how electrons behave in magnetic fields and interacts with other particles. Spin can take on two values, often called "up" or "down," which helps determine an electron's role in forming atoms, molecules, and materials. This property is crucial in explaining magnetism, the structure of matter, and modern technologies like quantum computing. In essence, electron spin is a fundamental quantum characteristic that shapes the behavior of electrons at the microscopic level.
