This ignition coil driver is a HOT one! From my recollection, it delivers a nastier spark than the legendary Ford Model T ignition coil. The circuit uses an inverted 555 oscillator that is coupled to ...

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in ...

Traditional automotive ignition systems can be either inductive discharge or capacitive discharge. Traditionally, old-school stock engines had inductive discharge systems that rely on the coil to do ...

The principle of action and reaction in Lenz’s Law states that an induced electromotive force (emf) generates a current in a direction which opposes the change in flux that caused the emf in the first ...
