Practitioners claim that subjecting certain parts of the body to weak electric or magnetic fields has beneficial health effects. Hemoglobin, the blood protein that carries oxygen, is weakly ‘diamagnetic’ (when oxygenated) or ‘paramagnetic’ (when deoxygenated). The magnets used in magnetic therapy are of a magnitude that is too weak to have any measurable effect on blood flow. This is not to be confused with ‘transcranial magnetic stimulation’, a scientifically valid form of therapy, or ‘pulsed electromagnetic field therapy’. It is believed that all our molecules have a certain ‘magnetic energy’ in them. When they go out of balance, certain health issues arise. So, the concept is; when the body is exposed to a proper magnetic field, abnormal cells become normal again.
