Abstract: | Organisms exposed to a combination of weak, parallel directed static and alternate magnetic fields show a distinct response when the frequency of the alternate component is formally equal to the cyclotron frequencies for Ca2+ or other biologically important ions. It is impossible to explain the observable phenomenon through a magnetoinduced drift of the ions, as the Lorentz's force is too small to change ionic movements. In similar conditions, a resonance-like response arises when the alternate field is tuned to the Larmor frequency for nuclear-spin magnetic moments. The mechanism of these phenomena is also still unclear. In the report, the arguments are presented to treat both types of effects in a single context for which the existence of ion magnetic dipoles is postulated. |
