Hi Lighty,
To my understanding, back emf and the collapsed coil's voltage potential are two different things that happen at two different times.
The back emf is happening at the exact same time that a current is induced into a coil. There is the forward induction and then the back emf is counter induced and is explained by the Lenz law.
After the coil is charged and the back emf event happens and the coil power is turned off, the build up magnetic field collapses in reverse polarity and fills the capacitor with voltage potential free or mostly free of electron current and therefore no back emf in that event since it is for the most part, just voltage potential and not current.
So when Bedini's circuits for example are charging capacitors, it does so with radiant energy or the voltage potential free of current instead of charging a capacitor with back emf or electron current.
Someone else may be able to clarify the distinction between back emf/counter current and voltage potential/collapsed field
