The electromagnetic induction principle underpins the operation of an inductor. An inductor creates a magnetic field around itself as electricity passes through it. Magnetic flux is the form of energy stored in this magnetic field. The square of the current and the inductor''s inductance determines how much energy is retained in the magnetic …

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 ...
