Interacting Magnetic Sources
A part from the Basic heating event approach we have also
investigated another basic heating event. In this case two flux sources are initially
partly connected. On the Sun these would be moved relative each other. If we as
an assumption say that the source are not rotating while being adverted, then the advection
results in a rotation of the sources relative each other.
Therefore to simplify the experiment it is assumed that the sources are fixes in
space, but both centred on a vortex flow. Stressing of the field from the vortex motions
initiates motions that propagates into the ambient system and stresses the
system. From the experiments, that are taking place right now, we have found that
the system can be rotated a significantly angle without significant changes in the
connectivity of the flux between the two sources. Eventually the shearing of the
field, due to the not ridged rotation, generates currents that numerically
allows the field lines to diffuse through the plasma. Until now we have not found
any significant localised current concentrations that could give rise to any
large and spontaneous energy releases - which is different to the Basic heating event
experiment. From comparisons with kinematic and time independent
expectations of the dynamical evolution, the full MHD experiment show a much
richer dynamical structure.
