DC Magnetic Field Measurements
DC magnetic fields (Magnetostatics) are measured by the deviation or fluctuation of flux density in µT as well as the deviation of the compass needle in deg. Sprung mattresses can reach anomalies between 4,000 and 60,000nT. Earth energies are measured by the Geiger Meter or by more expensive Scintillation counter.
