The Master Of Magnetics "Steven Mark"

I made reference to this in an earlier post when i described the coils as being connected in series. I think this is key to the resonance between the upper and lower coils.

Wow It?s only been a few days since I was here and it took me a while to read all the posts since then. I like to hear about the team effort people are talking about. I haven?t been posting much because I am busy wrapping coils and testing. Today I think would be a good day to post my findings. Attached is pic of a 3*2*.5 ferrite core. 32g mag wire is wrapped the same direction starting at T and tapped at each quadrant giving 4 quadrants or 4 separate coils labeled A 1-4 on the attached pic # 2. 28g mag wire is wrapped opposite but in the same direction counter clockwise around the core. The resistance for each noted in pic 2. I then used my handy USB interface board to drive 4 transistors in a counterclockwise direction. The software I wrote allows me to change the RPM / switching times of the transistors which drives the 4 coils of the A* coils. The experiment was used to understand the electron flow in the wires and the magnetic interaction. This is a different set up that what Tesla uses, I am only using DC and no phase difference to try to rotate a field around the core. I found I could get the compass spinning around but only to a certain speed once my RPM increased over a certain point the compass was confused. As well the ferrite core makes a sound when you pulse it unlike a steel core. I assumed that this would happen do to the specifications of the ferrite core. Experiment #2 involved checking back EMF from A1. The back EMF with the following measurements were noted. 9volts source pulled 200ma through a transistor driven by a 555 timer with 95% off and 5% on pulse. 190ma was drawn off the coil with a diode to receive only the back EMP pulse. The scope, set to x-y mode shows a large back emf spike around 50 volts but little intensity. Intensity is amps. This clicking of the ferrite core was the next thing I wanted to inquire into so I created an amplifying circuit. The circuit uses a small pnp transistor to drive the amplifier a typical amplifier, the base will work when a negative or electron is sensed. I then pulsed the core and listened to see if the click was amplified and yes it was. This amplifier also picks up lots of dirt like the 60 Hz of the electricity flowing in my house, so annoying. One thing I did discover is that at a certain on time of the pulse, very fast, a back emf spike would be produced a few milliseconds after the pulse on A1 and could be herd in the amplifier. Anybody know why the delay in the backemf on the driver coil? My next experiment will be using a flat coil inside the core to see what kind of wave or magnetism is generated in the ferrite core and coils.

@Kosh,

I read that post repeatedly and lost count. a magnet moving along the wire, which I assume is the length, causes no flux breakage. But the electrons in the wire still cause minute flux line breakage?
Or perpendicularly speaking, magnet speed across 1" = 1 unit and the same magnet speed across 12" = 12 units?

I am a EE and somewhow this goes against old knowledge.

Tnx, giantkiller.

giantkiller,

please expain? or give it your best shot.  are we talking about longitudinal electric transfer? if so, is there a 90 degree magnetic field associated with a longitudieal electric transfer?  if there is a 90 degree magnetic field, in a longitudinal electric transfer i think we can get back to perpindicular to the collector coils!  has anyone ever shown this?

lol
