Development of Measureing System for nT-order Magnetic Field Caused by Human Hands

Abstract

Studies report that some qigong masters or students can generate nT-order to 100nT-order magnetic field under their control. The authors developed a pilot system to measure the magnetic field caused by human hands. The pilot measureing system consists of a small magnetic shielding case(double box type)which shields human hands, magnetometers, amplifiers, a data sampling system and a monitoring system. Geomagnetic field was decreased about 1/1500 in the shielding case. Moreover, for the easy carrying, the magnetic shielding case could be disassembled into some parts and placed in handling packet. Results of the preliminary test confirmed, for example, that it is easy to detect nT-order magnetic field not caused by human hands. Next it is necessary to improve the way heat and moisture are removed.
