Electromagnetic fields in Biology
Electromagnetic waves and fields are manifestations of electromagnetic force. These are described by the Maxwell equations. Their source is the electric charge. Electromagnetic fields can be differentiated in electrical and magnetic fields.
The electromagnetic force is one of the four known fundamental forces, with which all phenomena und structures in the universe can be explained according to the current knowledge base. This force is responsible for all chemical bonds and reactions and as a result for any biological activity as well. Nuclear and chemical bonds are the result of electromagnetic interactions of atoms amongst each other. Hence, 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 also a weak low-frequency proportion that is known as the Schumann resonance ≥ 7.8 Hz.
Since the 1990s the health related effects of unnatural EMF such as mobile telephone emissions, WLAN or the AC mains power supply have been researched. The therapeutical benefits of EMF gain increased attention. With regards to the interaction of the low-frequency electromagnetic fields (LF EMF) with biological cells and tissues there are different biophysical theories. These are among others:
- Low-frequency magnetic fields cause a direct induction of electric currents and tensions
- Low-frequency magnetic fields interact with the Zyklotron-resonance of biologically relevant Ions in a constant magnetic field
- Formation of a Zeeman-splitting of spectral lines or binding conditions in atoms and molecules through an exterior magnetic field (Zeeman effect). For chemical processes the so-called radical-pair mechanism is a relevant example.
- Effects through magnetic particles (Magnetosome) in cells.
Proprietary CIT EMF
The characteristics of CIT fields are illustrated in the adjacent figure:
the magnetic field pulse is emitted with a defined repetition rate from a coil (B). The periodic emission pauses temporarily (A). A pulse can be described by its signal shape, pulse length and amplitude (C). The amplitude is the measure of the strength and intensity of the field. Currently used CIT fields differ with regard to their repetition rate and their send-pause-intervals.
