Which component is considered a basic part of the magneto system?

The magneto system is a crucial part of the ignition system in small engines, and its primary function is to generate the electrical spark needed to ignite the fuel-air mixture in the engine's combustion chamber. A fundamental component of this system is the use of permanent magnets.

Permanent magnets are essential because they create a magnetic field that induces electrical current when the engine is running. As the engine's flywheel rotates, the permanent magnets pass by the coils of wire in the magneto, resulting in the generation of electricity. This electricity is then used to create a spark at the ignition plug, thus igniting the fuel mixture.

Other components, such as a battery or starter motor, are part of the broader electrical system in an engine but do not play a direct role in the magneto system itself. A fuel injector is specific to fuel delivery systems, typically found in more advanced engine designs, but is not related to the magneto's function of ignition. Therefore, understanding the role of permanent magnets helps clarify why they are a basic part of the magneto system and critical for engine functionality.
