Magnifiers may allow faster energy transfer, reducing the time when current
is flowing in the lossy spark gap. With reduced energy loss the energy
ending in the top terminal increases. Without losses considered the maximum
output voltage with two or three coils, with the same primary capacitor and
total load capacitance, is the same.
