Interesting experiment with an transformer, 2 lamps, diodes and an magnet

...You would need an inductance meter to determine the coils inductance to assit you in selecting the correct cap value though.

Carl, unfortunately I dont own such a inductance meter. :-(

@ all replicators: Please notice there is a change in the circuit draft (again) new draft

Hi Markus,
you really have to measure input power and compare it
to both output powers at the 2 lamps.
Otherwise we would only suggest, that your
circuit is just at better efficiency, when you place the
magnet onto the core.
As this could influence the saturation of the core and this
way the energy transfer via the core, the core then could
just work as a better transformer and also store more energy
for the kickback Back EMF.
So to know, if thei circuit is overunity you must measure
input power and all output powers and compare them.

Many thanks.

Regards, Stefan.

Stefan,
look at this scopeshots I postesd already: klick here
Is it possible to calculate the power using the measured CycleArea-Values (see on the right of the scopeshots) for
current and voltage across the light bulbs?

To ask more precise: Is it possible to calculate power using this formula:
CycleArea of (current) x CycleArea of (voltage) instead of CycleArea of (current x voltage) ?

Where "x" means a multiplication and CycleArea means "Bereichsmessung einer Signalperiode in Vs"

Hi Markus,
yes, try to multiplicate the uVs value of the voltage measurement with the
uVs of the amperage measurement (via the shunt).
This then should give an energy  value. ( power x aquisation time)
Then divide through this aquisation time and you have the realtime power.

You have to find out from the manual, how the scope calculates
this uVs value over the time period. Is it just a average voltage or
a mean root square voltage ? (RMS voltage)
Then you could add or multiply in a correction factor.

P.S: Why does your scope also display uVVs so 2 Voltage "V" in the center ?
What is this ?
