Current increase at ICR (DC). Current increase through the glutamic acid /HCl solution (2.24 mM, pH = 2.85) at and near ICR conditions. The static magnetic field strength is B
= 40 μT, the amplitude of the alternating field B
is 50 nT, the frequency resolution Δf = 0.05 Hz. Course using a constant electrode voltage of 80 mV ("Zhadin's experiment").
