We have performed 3D numerical simulations to investigate the effect of partial ionization on the process of magnetic flux emergence. In our study. we have modified the single-fluid MHD equations to include the presence of neutrals and have performed two basic experiments: one that assumes a fully ionized plasma (FI case) and one that assumes a partially ionized plasma (PI case).
