Assuming a seed field of the order $10^{12}\\thinspace\\text{G}$, that is a common value for pulsars, one obtains its amplification due to such a novel mechanism by about five orders of magnitude, up to $10^{17}\\thinspace\\text{G}$, at time scales $\\sim (10^3 - 10^5)\\thinspace\\text{yr}$. This effect is suggested to be a possible explanation of the origin of the strongest magnetic fields observed in magnetars.
