A combined action of weak static and alternating low-fraquency magnetic fields on ionic currents through aqueous amino acid solutions (asparagine, argenine, glutamic acid, and tyrosine) were studied. Distinct (30-50% over the background current) narrow-band peaks for the frequencies close to the cyclotronic ones for the ionized forms of the corresponding amino acids were seen on the current versus frequency curve with alternating field direction being parallel to the static field. No other peaks were observed. The effects were completely reproducible. No effects were observed for perpendicular fields or absence of the static field. The effects were only observed for very weak alternating fields (0.05 mcT). The effect vanishes on increasimg the alternating field amplitude.

The influence of the joint action of constant and variable magnetic fields on the ionic current through an aqueous solution of an amino acid has been studied for asparagine, glutamic acid, arginine and tyrosine. In the curve of the dependence of current on the frequency of the variable field parallel to the constant distinct (30-50% of the background current) narrow-band peaks were observed at frequencies close to the cyclotron frequency of the ionized molecule of the corresponding amino acid. No other peaks were noted. The reproducibility of the effect is 100%. In perpendicular fields as in the absence of a constant field there is no effect. The effect is observed only for a very weak (0.05 μT) variable field. The effect disappears with increase in the amplitude of the variable field.
