This article describes a new area of research in which magnetic fields from the human body are measured at depths of 1 X 10*9 gauss, or approximately one billionth of the Earths magnetic field. An objects resonant frequency is the frequency at which it changes direction when subjected to external force. A human response to Earth-strength magnetic fields might seem surprising. From time to time, a scientific study finds a link between living near high-voltage power lines and illness. Its possible this tendency might be why previous researchers had trouble identifying this magnetic sense if they cranked up the strength of the magnetic field to help subjects detect it, they might have instead ensured that subjects brains ignored it. Skeptics dismissed early reports of these responses, largely because there didnt seem to be a biophysical mechanism that could translate the Earths weak geomagnetic field into strong neural signals. Typically, the strength of the magnetic field is much weaker than the corresponding physiological bioelectric signals. The first valid measurement was actually made in 1963,[1] but the field of research began to expand only after a low-noise technique was developed in 1970. As with any new practice, repetition is key to making it familiar to the brain as to the heart.
