How an Ignition Coil Works
Here's what's inside an ignition coil and how it works to increase the voltage to fire a spark on your car:
Here's a few photos of the ignition coil.
Starting with the coil, removed from my Toyota Corolla:
An ignition coil is located on top of an overhead cam engine. Its responsible for increasing voltage from the car's 12V to the thousands of volts needed to fire a spark in the combustion chamber:
When chopped open you can see the coil and other layers, along with the center iron core:
Here are all the components inside the ignition coil:
Here's a system diagram of how the ignition coil works electrically:
Note its the voltage spike caused by varying the electromagnetic field that fires the spark, and not just the step up transformer itself.
Enjoy!
