Scientific paper

In this paper, we present a simplified model for a magnetized neutrino-dominated accretion flow (NDAF) in which the effect of black hole (BH) spin is taken into account by adopting a set of relativistic correction factors, and the magnetic field is parameterized as β, the ratio of the magnetic pressure to the total pressure. It is found that the disc properties are sensitive to the values of the BH spin and β, and more energy can be extracted from NDAFs by using a faster spin and lower β.
