The proposed model attempts to bring more details into explanation of an intricate mechanism of endogenous ELF magnetic
fields generation in living cells.
It is based on hypothesis that ELF endogenous magnetic fields are initiated by cells as an integral part of their living
activities, including selective ion transport and intercellular communications.
Dynamic variations in length of cytoskeleton microtubules, attached to membrane microdomains were identified in (Cifra,
et al., 2007) as a driving force of cells membrane mechanical vibrations.
Resultant normal to surface vibrations of electrically polarized microdomains is the second part of this mechanism, in
which microdomains function as elementary magnetic antennas radiating locally biologically significant ELF magnetic field.
Besides cell-to-cell synchronization, the resultant endogenous magnetic field is employed by cells for selective ion transport
through specific ion channels associated with the microdomain.
For this, microdomain mechanical vibrations and associated magnetic field are tuned to cyclotron resonance frequency of
specific ion type, and facilitates this ion type dehydration.
The ions dehydration enables their energy-lossless penetration into channels, while the ion-selective channels mimic natural
electrical environment of hydrated ion in aqueous solutions (MacKinnon, 2003).
Remarkable susceptibility of ion channels to exogenous weak ELF magnetic fields tuned to specific ion resonance frequencies,
observed in numerous experiments, may be considered an indirect indication of existing build-in magnetic field sensing mechanism employed by living cells routinely for ion traffic regulation and corporative operation.
