back EMF I

Back EMF circuit (on the basis of single transformer coil) but applied to 6V battery can light 12V bulb or develop up to 70V capacitor charge and retain the same battery charged. Instead of relay I’m using 12V solenoid coil breaking the circuit (in a way similar to electric buzzer, it’s reduces overheating of contacts). Needa perform more tests in order to determine the true nature of back charging.
