a very high value, enough to spark across the gap of the spark plug. As the voltage of the primary winding rises to several hundred volts, the voltage on the secondary winding rises to several tens of thousands of volts, since the secondary winding typically has 100 times as many turns as the primary winding.

Impulse coupling, induction vibrator, and booster coil

Because the magneto has low voltage output at low speed, starting an engine is more difficult. Therefore, some magnetos have an impulse coupling, a spring-like mechanical
