This global electromagnetic resonance phenomenon is named after physicist Winfried Otto Schumann who predicted it mathematically in 1952. Schumann resonance frequencies are electromagnetic waves excited by lightning along the circumference of the Earth and considered to be the planet's magnetic frequency. Some experiments showed that by tuning into 7.83 Hz people experienced benefits like enhanced learning/memory, body rejuvenation, balance, improved stress tolerance, and grounding. The Schumann's low frequency of 7.83 Hz five octaves higher gives a tone of this fork 250.56 Hz. When this tuning fork is activated it produces the beneficial frequencies across all available octaves.
