This thread is about advanced and delayed magnetic field's-no lenz delay PLEASE
Below is a video of a generator that uses two ferrite C core's to form the complete ferrite core assembly. As you will see in the video,the secondary coil recieves most(about99%)of it's magnetic flux from the primary coil(once the primary is loaded).How ever,there seems to be a bit of a mystery here,as the current in the secondary is leading in phase when the load is reduced. This brings the question-->how can it be recieving the magnetic field from the primary before the primary starts to produce current?.

It should also be noted that the secondary(regardless of load) in no way reflects a CEMF to the rotor. So enjoy the video,and post your thoughts.

Very nice.  This will be an interesting topic I am sure.  You are off to a good start.

Cheers Bill.

The next step is to make it solid state,and use an electromagnet insted of the rotor. In saying that,dose anyone have a simple DC to AC converter that is triggered by an SG-so as to be able to raise and lower frequency. Im not looking for any space shuttle schematic's,but more a very simple and robust one. I was thinking along the lines of a push/pull circuit,unless some one has even a simpler one?.

Cheers

HI Brad
I see you answered MarkE's question about having the dots mixed up in the video, so that _probably_ takes care of that issue. Could you take a look at my sketch below, and tell me if it accurately represents your circuit and the measurement points?

As far as the DC-to-AC circuit you are asking about, there are several ways to do it, but the easiest way requires a bipolar DC power supply that will supply -V to 0 to +V. Most dual-output DC supplies can be configured to do this, if you can put the two outputs in series. You use the negative of one output for -V, the common (+ of one connected to - of the other) for 0 and the positive of the other output for +V. Also very easy to do with two batteries in series. The circuit that I used for the MescalMotor driver is an example that you could easily adapt for your purpose, subbing the SG for the photosensors or potentiometer in that circuit.
The 741 op-amp is easy to use, common as dirt,  the standard supply voltage is -15_0_+15 for the op-amp but it will work on quite a bit less and your FG will have no trouble driving it. Give it a sine wave input and the output will be a sine wave, square wave input, output square wave, etc. The feedback connection cleans up the pulse shape on the output. You can have the power pushpull stage switching as much as the transistors can handle (careful about that feedback connection though). See below for the basic circuit. Op-amps are mega-cool!

ETA: Oh, I see that I may have one of the rotormagnet polarities wrong. I think you are using alternating polarities rather than all one polarity up, right?
