  3. A bit yeah. But an ignition "coil" is really two coils. A car ignition coil is a step up transformer. The car's ignition system runs the coil on pulsed DC. So the primary is constantly being switched on and off. This video did not really touch on magnetic coupling of currents between conductors. But that's something else we do with inductors a lot.

  4. This is not easy stuff to understand. People who were arguably brilliant had to struggle to discover all of this. They weren't correct immediately either.
