In quantum medical area, the fundamental reason for people suffering disease is that the spinning and the orbiting of the electron have changed, which makes the atoms change, which causes the biological micromolecule change. Therefore, the biological macromolecule changes, gradually, the whole cell starts to change, and ultimately the whole organ change. Since the electron is a charged body, when the spinning and the orbiting of it have changed, the electromagnetic waves inside will change accordingly. The energy of electromagnetic wave variation, which is caused by the different states of diseses and nutrition, is very weak, usually only Ns Gaussian or To Micro-Gauss. The frequency and the energy of the magnetic field are measured by holding the sensor with hand. It is similar to the theory of listening to the radio. There are various wireless waves in the air, but if you want to listen to certain broadcasting station, you should modulate the radio to the same frequency, which causes the resonance, and then, the radio can get the specific radio station. Quantum resonance magnetic analyzer is based on this theory as well.
