Abstract:	When modeling coronal loops by calculating the potential field from magnetograms it is often found that field lines highlighted of the potential field do not match the coronal loops observed in the data. To rectify this situation, we construct a non-potential field in which helical “twisted” currents with prescribed radii are inserted along certain potential field lines. We then relax the magnetic field to a non-linear force-free field (NLFFF) using magneto-frictional relaxation. In doing so, we find that we are able to approach a geometrical match between the field lines and the coronal loops observed in AR 10938 on January 18, 2007.
