What is a magneto ignition system?

A magneto ignition system is indeed a self-contained unit that generates electrical current without relying on an external power source. This system is essential in small engines, like those found in lawnmowers or chainsaws, where compactness and reliability are critical.

The magneto works by using a rotating magnet that induces an alternating current in a coil of wire, which then transforms the current into a high-voltage spark capable of igniting the air-fuel mixture in the combustion chamber. Because it is independent of batteries or external electricity, it is particularly useful in environments where maintaining a battery can be challenging.

This self-sufficiency contributes to its widespread utilization in various small engine applications, ensuring that the engine can start and run effectively without the need for a constant external electrical supply.
