A spinning charge generates a magnetic field, as shown by the animation on the right. The resulting spin-magnet has a magnetic moment (μ) proportional to the spin.2. In the presence from an external magnetic field (B 0), two rotation states subsist, +1/2 and -1/2.The magnetic moment of the lower energy +1/2 state is aligned with the foreign field, …
