This library can be used to compute the magnetic field and the magnetic vector potential of filamentary current carriers in the form of a circular loop and straight segments. Arbitrary geometries of conductors can be approximated by a polygon along its contour and the connecting segments between the polygon vertices are modeled by straight segments. Finite-width conductors can be approximated by arranging multiple filaments throughout the cross section of the current carrier.
