Re: [EVGRAY] Florist wire and BiTT core

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.

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