Curvature of the Field Lines of Magnetic Braids

In this paper, we calculate the curvature numerically as a geometrical feature of the field lines of the magnetic braid that introduced by Antonia Wilmot-Smith and other new braid introduced in this work similar to that given by Wilmot-Smith but with four twisting regions are rotating one-by-one clockwise and anti-clockwise. The numerical calculation shows that the curvature of the field line of the new-version of the magnetic braid is much bigger than the curvature of the original model (Wilmot-Smith braid).
