Abstract
In the present work the results of the known investigation of the influence of combined static (40 μT) and alternating (amplitude of 40 nT) parallel magnetic fields on the current through the aqueous solution of glutamic acid, were successfully replicated. Fourteen experiments were carried out by the application of the combined magnetic fields to the solution placed into a Plexiglas reaction vessel at application of static voltage to golden electrodes placed into the solution. Six experiments were carried out by the application of the combined magnetic fields to the solution placed in a Plexiglas reaction vessel, without electrodes, within an electric field, generated by means of a capacitor at the voltage of 27 mV. The frequency of the alternating field was scanned within the bounds of 1.0 Hz including the cyclotron frequency corresponding to a glutamic acid ion and to the applied static magnetic field. In this study the prominent peaks with half-width of ~0.5 Hz and with different heights (till 80 nA) were registered at the alternating magnetic field frequency equal to the cyclotron frequency (4.2 Hz). The general reproducibility of the investigated effects was 70% among the all solutions studied by us and they arose usually after 40–60 min. after preparation of the solution. In some made-up solutions the appearance of instability in the registered current was noted in 30–45 min after the solution preparation. This instability endured for 20–40 min. At the end of such instability period the effects of combined fields action appeared practically every time. The possible mechanisms of revealed effects were discussed on the basis of modern quantum electrodynamics.
Highlights
The middle of the eighties was marked with the discovery by Blackman [1,2] of a surprising phenomenon: a low frequency alternating (AC) magnetic field (MF) changed free calcium concentration in nervous tissue only in the presence of a simultaneously acting static (DC) MF
The outcome of our present investigation confirmed the results of the original work [17] and of further works [18,16] devoted to replication of the original experiments: the height and half-width of the resonance peak of the current through the glutamic acid solution at the cyclotron frequency of AC MF were comparable with those in the above works
Most likely it was due to longer duration of AC MF exposition applied in our work in every point of AC MF frequency as well as to the accuracy of the exposures provided in our facility in Rome, equipped with a patent pending exposure system, developed by Italian CNR and ISPESL institutions
Summary
The middle of the eighties was marked with the discovery by Blackman [1,2] of a surprising phenomenon: a low frequency alternating (AC) magnetic field (MF) changed free calcium concentration in nervous tissue only in the presence of a simultaneously acting static (DC) MF. The most prominent effect was observed at the AC field frequency close to the cyclotron frequency of a calcium ion.

These works opened a new line of research in Bioelectromagnetics. Afterwards, many confirmations for these data were obtained in works performed on different objects and in different experimental situations [4,5,5,7,8,9,10,11,12,13] which captured the interest of the scientific community about the existence of the above effects
