Its calculation involves a cross product, but certain physical properties of this operation are not fully satisfactory. This article proposes a modification to the Biot-Savart formula by replacing the vector field with a scalar field. The revised magnetic field concept is then applied to both short and long electrical segments. %K Electrical Segment with Magnetic Field %K Biot-Savart Law %K Magnetic Field Value %K Scalar Field Value %K Equipotential Surface %K Equipotential Curve %K Field around Electrical Segment %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=141837
