The secondary winding of the magneto coil typically has how many times more turns than the primary winding?

The secondary winding of a magneto coil is designed to have a significantly higher number of turns compared to the primary winding. This configuration is critical for generating a high voltage necessary for ignition in small engines.

A common design ratio in magneto systems is that the secondary winding has around 60 times more turns than the primary winding. This high turn ratio is essential because it allows for the transformation of the low voltage generated in the primary winding into a much higher voltage in the secondary winding. When the magnetic field in the primary winding collapses, the quickly changing magnetic field induces a current in the much larger secondary winding, resulting in a high-voltage pulse suitable for igniting the fuel-air mixture in the engine's combustion chamber.

The other options reflect ratios that are not typical for most magneto coils. A turn ratio of 10, 30, or 100 is either too low or excessively high for standard applications in small motors, which helps emphasize why 60 is the most accurate answer.
