Final answer:
A safety gap in a magneto prevents excessive voltage buildup and ensures device and user safety.
Step-by-step explanation:
A safety gap in a magneto serves the purpose of preventing excess voltage buildup and ensuring the safe operation of the device. It acts as a protective measure by providing a path for the spark to jump across, limiting the voltage that can be generated.
For example, if the wires of the magneto coil are too close together, there is a risk of a high voltage spark jumping across and damaging the magneto or causing a dangerous electrical shock. The safety gap introduces a controlled distance between the wires, allowing the spark to occur at a safe level without causing harm.
In summary, the purpose of a safety gap in a magneto is to prevent excessive voltage buildup and ensure the safety of the device and the individuals interacting with it.
