What component of the magneto ignition system is responsible for converting low voltage into high voltage?

The component responsible for converting low voltage into high voltage in a magneto ignition system is the coil. This coil is typically referred to as the ignition coil, which plays a crucial role in the ignition process of small engines. Inside the coil, there are two windings: the primary winding and the secondary winding. The primary winding is connected to the low-voltage power source, and when the current flows through it, it creates a magnetic field. When the current is interrupted, this magnetic field collapses and induces a higher voltage in the secondary winding. This high voltage is what is necessary to create a spark at the spark plug, igniting the fuel-air mixture in the combustion chamber.

In this context, other components like a transistor, capacitor, and resistor do not perform the primary function of voltage conversion in the ignition system. A transistor may be used for switching and controlling current, a capacitor typically serves to store and release electrical energy, and a resistor is used to limit current within a circuit, but none of these components are responsible for generating the high voltage needed for ignition.
