Non-linear force-free field models of small-scale solar magnetic fields
Karen Meyer, Duncan Mackay and Aad van Ballegooijen


We model the dynamical evolution of the Sun's magnetic carpet, and construct a non-linear force-free coronal field based on surface motions. Rather than independently extrapolating the coronal field at each time step, we model a continuous evolution of the field through a magnetofrictional relaxation technique. So far we have studied energy build up within the field due to the basic interactions of cancellation, emergence and flyby. The code will later be applied to magnetogram data, and the simulated coronal field compared to structures seen in observations.
