Its electron spin has energy levels that change with the magnetic field around it. Researchers shine green light on the diamond, detect its red fluorescence, and sweep microwave energy. A change in fluorescence reveals the spin transition—and helps infer the field. One NV center can favor spatial resolution. Many centers can favor stronger collective signal. Neither choice turns a sensor into an all-purpose answer; it sets a measurement trade-off. A diamond can turn an atomic-scale defect into a magnetic-field ruler. https://t.me/ProjectSentinelTech
