| Abstract: | The dual energy principle in energy calculation is recounted in this paper.The convex functional and the concave-functional of static magnetic fields are developed by analyzing the influence of Lagrange's multipliers on the stationary values of energy functional.The upper bound and lower bound of the magnetic field energy,caused by the current going through the cross section of complex shape and the equivalent inductance corresponding to the magnetic field are calculated. |
