We show that such parametrization models non-linear electrodynamics in the early Universe and investigate the cosmological viability of the model. In our scenario, the early dark energy is encoded in the non-linearity of the electromagnetic fields through a parameter $\\beta$ that changes the Lagrangian of the system, and the parameters $\\gamma_s$ and $\\alpha$, that define the departure from the standard model constant equation of state.
