Faraday''s law: The foundation of ignition coil function
While Lenz''s law relates to the rate of current flow change in an inductor as it saturates (ignition coil primary windings), Faraday''s law relates to the resulting inductive kick that occurs when that current flow ceases and that ignition coil discharges. And this is the basis for our topic of discussion today (Figures 3 and 4).

Injector Waveform
The voltage applied to the coil in the waveform under discussion when opening the injector is about 84V, much higher than the 24V available from the battery.
