According to the laws of Quantum Physics, everything in the universe has a unique energy signature or resonance.
The M-Field plays a role in the body's extension of the autonomic nervous system that is searching the body's immediate environment for matching or mismatching resonance.
The M-Field will show interest in a matching resonance. (Attraction)
Conversely, it will not be interested in a non-matching resonance. (Rejection)
With a matching resonance/attraction,the muscle being tested will remain strong.
With a mismatched resonance/rejection, the muscle being tested will become weak.
