@all

no matter how many coils and turn ratio you put on your transformer, the current passing through them will be the same in all coils.

it does not mean you will have, more on the pickup coils, then what the primary have passing through it, Lenz's law will always apply.

there are reasons to use multiple pickup coils.
getting less lost of what the primary is providing is one.
but getting more then what the primary(ies) is/are feeding is not one of them.




@MrMag
you are right, there is no ou involved.
but you have to agree that there is something realy interesting about the kicks...



@Pardon
flyback does not mean polarities are reversed.
there are a few posted jt's scope pictures that will prove this to you.

This could be done with a collapsing magnetic field, the collapse of the flux could generate a more powerful volt/amp pulse than source.

do you have proofs of this ?

my current understanding of this magnetic field collapse is: it is equal to the emf that have induced it.
only the time frame change, not the energy.

@jeanna

Nice scope shot , is that from the mk style cross wind pickup coil ?

@the nop  and all

Thank! That being said there is not more energy out then in but the fact is that energy can be used for many different things
at a same time , it just a mater of having the coils for it.

Ok so its not more but the same energy on many output , we are used to linear pattern but this is not, we usually use the power we got to do one thing at a time , this is better , its not more energy but better usage of the energy.

Does anyone here know what the leads on these components are made of?  Tin perhaps?  the transistor, the LED or the diodes?

Thank you!

@Mk1

Thank you!

@ALL

I just got a new toroid from an old power supply and plan on getting a new fluke scope and a Hall probe. I think there is something very intresting about this whole JT concept and have been working 15 hour shifts to fund some advanced research! If anyone can make any recommendations on Magnetic field probes I would love some link's. I plan to map the Toroid out in FEMM and have full scope readings and V/A on each pickup coil.

Take care!
