Magnetic element tracking has been widely used to study the transport and diffusion of the magnetic field on the solar photosphere. From the analysis of the displacement spectrum of these tracers, it has been recently agreed that a regime of super-diffusion dominates the solar surface. We present in this work the analysis of the diffusion of emerging new bipolar magnetic elements for different initial separation of the footpoints. The displacement spectrum for bipolar couples interestingly shows a similar behaviour with respect to the case where all magnetic pairs are considered. To understand how such peculiar diffusion in the solar atmosphere takes places, we compare the displacement spectrum exploring the initial maximum separation parameter.
