Ford Fokus>> Ignition system>> The ignition coil
In the ignition coil there are two windings: a primary winding with smaller number of coils (100) from a thick copper wire section 0,6 мм2 and secondary — 1000 coils from a thin copper wire section 0,1 мм2. Both windings clasp the steel lamellar core. The primary winding receives pressure from the onboard electric system of the car, thanks to it there is a magnetic field which crosses a secondary winding. If the management block interrupts current passage on a primary winding as a result of an induction the secondary winding makes pressure over 30 000 Century
