Schumann resonances are electromagnetic oscillations of the Earth’s electromagnetic activity. The process of calculating it is elaborate and beyond the scope of this space in the article. They can be generated, as well as the natural wave responses, using the Schumann resonance calculations. The sensors that measure the Schumann resonance comprise two horizontal induction coils. These measure the east-west and north-south components and features. There is a vertical electrical dipole antenna, and it is used to measure the vertical Schumann resonance component of the earth.
