DougThat is the nicest coil core anyone has made since I suggested using it way back in Bedini days. I haven"t even made one as nice as that.I eagerly await to see how it performsCheers Warren

Hi Kone, guys
If you are going to make a core this way, it is important to make sure the
outer loop is about twice the thickness of the inner drive loop.
This is to make it easier for the back EMF flux to go around the outside
loop rather than re entering the drive loop..... affecting the input
impedance on load.

The setup works best when the permeability of the centre drive loop
magnetic core circuit is high in comparison to outer loop.
So permeability of the outside magnetic loop circuit  (where the load coils
are mounted) ..nice low permeability needed here.
Also thickest cross section area and shortest magnetic path length from one
load coil to the other load coil ..if possible.

The one in the photo posted doesn't seem to have sufficiently thick outer
loop.

 I will  double, maybe triple, the thickness of that outer trainqular loop to my florist wire BiTT

Hi Gerry, Kone,

Here is how Tesla made a transformer with a magnetic screen between the windings. US PATENT 433,702:

 Hi Kone, For me painted florist wire, which just has a thin paint coating works better than plastic coated wire.
 As when its tightly packed it has more metal per square inch & less 'air' space between the flux conductors.
 

 For a current experiment I am using "Blossoms by Vivaldi" brand florist wire, it is only 130 gauge tho (in 113 gram packet) which is likely a bit small diameter.
 I'm down under in Australia here...you guys most likely have better range to choose from up there in the real world.
 

 What I do is wind the florist wire very tightly around the back end of a small drill bit to make long lengths of hollow steel coils.
 Then I feed a varnished copper wire up the centre of the coil.
 

 See attached picture.
 

 Then I use this copper with steel jacket wire as the primary or secondary of a transformer.
 When the copper wire develops it's magnetic field whilst carrying current.
 The field can't get out out of the steel jacket until it saturates the steel.
 

 This causes a delaying effect so that the transformer core doesn't become magnetised till a bit later in the input drive cycle.
 So the load winding doesn't 'feel' the input current's flux till a bit later on.
 By the time the back emf flux gets back to the steel shield .... if lucky we can cause the input current to increase (via back emf effect) whilst the input voltage is past 90 degrees.
 

 Giving a Cosine value which is negative. so E times I times Cos phi is negative answer, so effectively making a negative resistance, which can create power rather than consuming it. 
 

 Using the wire made this way also has some other interesting effects on it's own too.

 ps the paint gets hot & smells pretty bad at high power levels.

Hi Ole, g'day  Yes have seen this beaut Telsa patent which is exactly the idea.
 

 As we know energy can be temporarily stored and used a little later on.
 Preferably at right time in the ac cycle.
 As long as the storage method is efficient enough so losses don't exceed gains.
 

 I have not been able source really fine steel wire down here for this approach and it takes many many turns to be effective. 
 Thinking some metglass tape layers might work well as relative permeability is so high but saturation point is high as well so not much thickness likely required. 
 Have to be careful not to form a closed loop tho as it's just a big short circuited turn then.
 

 I also mounted a power transformer (toroidal) in a shortened jam tin with concentric steel sheet up through the centre then cut an opening around the top under the lid.  I covered it in masking tape & painted it with a thick layer of magnetic paint.
 Then wound a secondary on the outside of the tin similar to the "Gabriel Device" ..see on Youtube etc.
 

 Overall it was a dismal fail for me as those sneaky flux lines seem to creep through everywhere.
 

 I am used to failure, it's you guys here that inspire us with extra info etc, to keep at it.
 

 thanks Gerry

Hi Gerry
 very cool transforem idea with the florist wire - I don't trust the green enamel to hold up under much vibration or heat and would think it would have this coating wear down after awhile and cause electrical short-circuits so maybe wear throwaway rubber gloves and coat the florist wire with epoxyas it is being wound up just to make sure....with my Bi\TT cores too, I could of done that too but don't think "magnetic" short circuits with these cores is going to matter that much but maybe it will over time and affect performance with high frequencies I don't know.
 Maybe making cores inside a coil with florist wire..such as inside a torroed coil as in an ORBO motor and pulse both that inner coil and alsow the torroid too to cancel the field and make it go too...
 there is lots of florist wire on ebay of different thicknesses mine is .0.9mm thye had thinner but this seems good...
 I made "pinipoint" cores out of bundled florist wire in my muller generato coils, with just one 10mm length in center of bundle projecting and pointing towards the rotor magnets, while it gets gradual thicker clusters towards back of coil hoping to move bloch-wall back away from rotor magnets also to get some sort of delayed effect not sure if it does much but Robert Myrland did something like this with hiperco50 core material in his RV-Muller that looped...
