Calculate Inductance of the Two-Wire Line (3/3)
Inductance is calculated via flux linkage
The same result can be obtained using the energy of magnetic field.

Mechanical force acting to the wire (2/2)
Integration contour defines the closed surface.
Only X-component of the force makes sense.
The Y-component vanishes due to symmetry.
