  Abstract:
In this article we investigate the Hall effect in a standard magnetized accretion disc which is accompanied by dissipation due to viscosity and magnetic resistivity; By considering an initial magnetic field, using PLUTO code, we perform a numerical MHD simulation in order to study the effect of Hall diffusion on the physical structure of the disc. Current density and temperature of the disc are modified significantly by Hall diffusion,while the global structure of the disc is not affected substantially. This change in the current densities and the temperature of the disc lead to a modification in the disc luminosity and radiations.
