What is the purpose of the ignition coil?

The ignition coil is a crucial component in an internal combustion engine's ignition system. Its primary purpose is to convert the low voltage from the battery into a high voltage needed to create a spark at the spark plugs. This spark ignites the air-fuel mixture in the engine's cylinders, enabling combustion and powering the engine. Essentially, the ignition coil ensures that the engine starts and runs smoothly.
