  We present a novel Hall magnetohydrodynamics (HMHD) numerical simulation of a
three-dimensional (3D) magnetic flux rope (MFR) -- generated by magnetic
reconnections from an initial 3D bipolar sheared field. Magnetic reconnections
during the HMHD evolution are compared with the MHD. In both simulations, the
MFRs generate as a consequence of the magnetic reconnection at null points
which has not been realized in contemporary simulations. Interestingly, the
evolution is faster and more intricate in the HMHD simulation. Repetitive
development of the twisted magnetic field lines (MFL) in the vicinity of 3D
nulls (reconnection site) is unique to the HMHD evolution of the MFR. The
dynamical evolution of magnetic field lines around the reconnection site being
affected by the Hall forcing, correspondingly affects the large-scale
structures.
