Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up ...
Basic Principles of Inductor Coils. When electric current starts to flow in a conductor, a magnetic field is established around the conductor in the direction of the right-hand thread.

The ''constant-flux'' concept has been described in a recent Letter as a way to utilise space more efficiently for inductor geometry with the core enclosed by winding. While the concept can conceptually be extended to the companion case of the inductor with winding enclosed by the core, structural synthesis is complicated by the absence of circular symmetry.
Although the result may seem like something out of a freak show at first, applying the definition of the exponential function makes it clear how natural it is: ex = lim n → ∞(1 + x n)n. When x = iϕ is imaginary, the quantity (1 + iϕ / n) represents a number lying just above 1 in the complex plane.
