Behavior of Charged Particles in a Biological Cell Exposed to AC-DC Electromagnetic Fields

Abstract

Abstract Exposure to electromagnetic fields is a research area that has generated conflicting results and thus uncertainty about possible adverse biological effects. This article analyzes the behavior of charged particles in a biological cell when exposed to different combinations of AC-DC electromagnetic fields, by combining the Ion Forced-Vibration theory with the Ion Cyclotron Resonance and Ion Parametric Resonance theories. We analyzed (i) the physical mechanisms caused from resonance response and noise; (ii) the behavior of the particle when exposed to these fields with different combinations of initial position, initial velocity, field strengths, frequencies, and relative angle between AC-DC magnetic fields; and (iii) the particle behavior with certain values of the ratio BAC/BDC, where BAC and BDC are the strength of AC and DC magnetic fields. Our results show that the influence of combined AC-DC magnetic fields on particle displacement is larger than that of an AC magnetic field alone. The study i...
