title: Matching between theoretical and experimental data for ELF ion transport effects.
abstract: In recent years, several studies have been focused on the problem of nonthermal interaction between extremely low-frequency (ELF) electromagnetic fields and cell environment at membrane level. In the paper, to analyse the dynamic effects of weak static and harmonic fields on charged particles, some new considerations have been developed, based on the Lorentz model. The authors have reached a suitable formulation so that the data processing has led expressly to the evaluation of ionic-velocity components against magnetic-field amplitudes and frequencies, as well as a viscosity parameter. Even through a direct and rough comparison, the results of the authors' investigation have demonstrated an interesting agreement with some experimental data relative to ionic fluxes through cell membranes. Indeed, by means of an algorithm based on the techniques of the inversion theory, the author's have found definite values of the viscosity parameter for which the expected resonant behaviours (amplitude and frequency windows) fit existing experiments well. It seems worthy of interest that such viscosity values fall within a consistent, narrow range of low amplitude.
