Additional magnetic field values can be found through the magnetic field of a finite beam, for example, that the magnetic field of an arc of angle and radius at the center is , or that the magnetic field at the center of a N-sided regular polygon of side is , both outside of the plane with proper directions as inferred by right hand thumb rule.
