The idea behind any ignition system is to generate an extremely high voltage -- on the order of 20,000 volts -- at exactly the right time. The voltage causes a spark to jump across the spark plug's gap, and the spark ignites the fuel in the engine. See How Car Engines Work or How Two-Stroke Engines Work for details. See more The idea behind a magneto is simple. It is basically an electrical generator that has been tuned to create a periodic high-voltage pulse rather than continuous current. An electrical … See more When the magnets fly past the U-shaped armature, they induce a magnetic field in the armature.
