  Three-dimensional (3D) magnetic nulls are abundant in the solar atmosphere,
as been firmly established through contemporary observations. They are
established to be important magnetic structures in, for example, jets and
circular ribbon flares. While simulations and extrapolations support this, the
mechanisms behind 3D null generation remain an open question. Recent
magnetohydrodynamics (MHD) simulations propose that magnetic reconnection is
responsible for both generating and annihilating 3D nulls, a novel concept.
However, these simulations began with initial magnetic fields already
supporting pre-existing nulls, raising the question of whether magnetic
reconnection can create nulls in fields initially devoid of them. Previously,
this question was briefly explored in a simulation with an initial chaotic
magnetic field. However, the study failed to precisely identify locations,
topological degrees, and natures (spiral or radial) of nulls, and it
approximated magnetic reconnection without fully tracking field line in time.
In this paper these findings are revisited in light of recent advancements and
tools used to locate and trace nulls, along with the tracing of field lines,
through which the concept of generation/annihilation of 3D nulls from chaotic
fields is established in a precise manner.
