Larmor precession is the precession of a magnetic moment about an applied magnetic field. For a spin with gyromagnetic ratio and Hamiltonian , its expectation obeys . A spin coherent state retains its coherent form during this rotation.

Larmor precession is the phenomenon in which the magnetic moment of a particle (such as an electron or nucleus) precesses around an external magnetic field. This occurs when a charged particle with a magnetic moment is placed in a magnetic field, causing the axis of the magnetic moment to rotate or "precess" around the direction of the applied field.
