O.K., great stuff. I have a question lingering in the dark recesses of my mind going way back to Electronics 101. You say the longer the points stay closed the "more coil saturation" you get?
Isn't it true that once saturation is reached, you can let primary current flow until doomsday and you get no further magnetic field build-up?
So I guess the second part of my question is - is
coil saturation the right term to use when the points are closed and primary current is flowing?
