Abstract
We investigate the influence of a strong interior magnetic field on the structure and composition of a protoneutron star allowing quark-hadron phase transition. In contrast to protoneutron stars with noninteracting quark phase, the stars with interacting quark phase have smaller maximum star masses than those of neutrino-free stars. The strong field makes the overall equation of state softer compared to the field-free case favoring the evolution of a protoneutron star more towards a neutron star than a black hole.
