The Influence of the Extremely Weak Alternating Magnetic Fields on the Regeneration of Planarians and the Gravitropic Response of Plants
The influence of extremely weak alternating magnetic fields (EW AMF) directed colinearly to the static Еаrth magnetic field on the rate of regeneration of planarians and the rate of gravitropic response in the stem segments of flax has been studied. The value of bioeffects of EW AMF is determined by the parameter γ<i>B</i><sub><i></i>AC</sub>/<i>f</i>, where γ is the gyromagnetic ratio of the magnetic moments induced by the orbital movements of electrons in atoms, and <i>B</i><sub><i></i>AC</sub> and <i>f </i>correspond to magnetic induction and frequency of the alternating magnetic component. It was shown that the magnitude of bioeffects depends on the amplitude (at fixed 1000 Hz - frequency) and frequency (at fixed 192 nT - amplitude) of the alternating component. Maxima of bioeffects are observed at γ<i>B</i><sub><i></i>AC</sub>/<i>f </i>= 0.9; 2.75, and minor maxima γ<i>B</i><sub><i></i>AC</sub>/<i>f </i>= 4.5; 6.1. The bioeffects are absent at γ<i>B</i><sub><i></i>AC</sub>/<i>f </i>=1.8, 3.8, 5.3, 6.7. The positions of the maxima and minima of bioeffects correspond to the theoretical prediction (at γ = 14000 Hz/µТ). Primary targets for the EW AMF of this type are the magnetic moments induced by the orbital movements of electrons in atoms.
