Notably, considering an inflation-inspired power-law type magnetic field power spectrum of the form $P_B(k)\\propto k^{n_\\mathrm{B}}$ (where $n_{\\rm B}$ is the magnetic spectral index), we show that the VIGW signal is enhanced for stiff post-inflationary EoS, with the maximum enhancement happening for $w=1$.
