What role does the armature play in the ignition system?

The armature plays a crucial role in generating the spark needed for ignition in an engine's ignition system. It is part of the magnetic system found in components like an alternator or a magneto. As the armature rotates within a magnetic field, it creates an electrical current through electromagnetic induction. This generated current is then utilized to produce a high-voltage spark at the ignition coil, which ignites the fuel-air mixture in the engine's cylinders.

By converting mechanical energy into electrical energy, the armature ensures that the spark occurs at the right moment, facilitating the combustion process that ultimately powers the engine. Understanding this function is vital for diagnosing issues within the ignition system and maintaining engine performance.
