Studies report that some qigong masters or students can generate nT-order to 100 nT-order magnetic field under their control. The authors developed a pilot system to measure the magnetic field caused by human hands. The pilot measuring 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 a 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.
