Question #1
Need to know if there is an iron core in the solenoid. That makes a
big difference in the inductance. But from my experience using
commercials coils, the voltage could be a few thousand volts. I
could draw pretty large sparks. You can hook up a small neon bulb
across the inductor and watch it light up as you switch off the
battery. These bulbs take 70 volts to light.
Question #1
Not quite. The coil in a car is actually a transformer, with the
primary switched off and a secondary of many, many turns providing
the high voltage.
