Electromagnetic waves and fields are manifestations of electromagnetic force. These are described by the Maxwell equations. Their source is the electric charge. Furthermore, electromagnetic fields can be differentiated in electrical and magnetic fields.
The evolution of all biological life on earth has always taken place under the influence of magnetic fields, for example the earth's magnetic field. In addition to the time constant proportion of the earth's magnetic field there is a weak low-frequency proportion that is known as the Schumann resonance (cavity resonance between the ionosphere and the earth surface) ≥ 7,8 Hz.
The cell information therapy utilises pulsed electromagnetic fields with pulse repetition rates (frequencies) between 3 and 100 Hz.; therefore this method belongs to the area of low-frequency EMF. Higher-frequency portions of the frequence spectrum of the CIT fields reach measurably up to the lower MHz-range. The CIT pulse with the current form of application reaches up to a field strength of 300 µT and is therefore a factor of 6 to 7 higher than the earth's magnetic field. However due to the pulses being very short, the temporal-average intensity is lower than that of the earth's magnetic field.
