The SQUID magnetometer, a new device used by conventional researchers, measures biomagnetic fields
emitted from the heart, brain, and muscles.
However, much of the focus of Energy Medicine is on biomagnetic fields, which (in contrast with bioelectric fields) are not significantly attenuated as they pass through body tissues.
This discovery confirmed Saint-Gyorgyi's suggestion of semiconduction in the living matrix and gave a basis for the use of magnets and biomagnetic fields in healing.
In these studies, a superconducting quantum interference device (SQUID) magnetometer measured large biomagnetic fields emanating from the hands of therapists when they relaxed into their meditative or healing states.
