The coil is really a transformer. Transformers only work when there is a cycling input or alternating input. The primary (6 or 12 volt) side has fewer windings than the secondary (high voltage) side. When the points open the primary field collapses and induces a current in the secondary side which causes a spark to ground on the secondary side. Since power is power (watts) the secondary side has a higher voltage but a lower current than the primary side. The system cannot boost power but instaed the power remains the same on both sides of the coil. My 2 cents.
