Looks like the measurement data will be available only in first or second week of March .
Meanwhile hitting in the dark continues for me.

I have decided to go in reverse. Setting up the output side first with continuous monitoring of P_out in a resistive load. By doing this, I will be able to see the effect on the output by varying input parameters one at a time. The input parameters are:

1- The input current
2- Core material (BH properties)
3- Air gap between core and the rotor magnet pair
4- Number of turns (Inductance)
5- Vertical position of the coil
6- Biasing magnets
7- Number of coils
8- Pulse width
9- Duty cycle
10- And some more ...

Output parameters are:
1- Number of rotor magnets
2- Number of generator magnets
3- Number of generator coils
4- Polarity
5- Rotor weight
6- Rotor size
7- Friction
8- Load
9- Air core or iron core
10- Air gap

By fixing the output parameters to some value, one can find optimal input parameters, then switch back to output and find optimal output parameters. This is a very difficult engineering task and will need high precision adjustments.

The SKDB materials talks about the M-H Curve and Magnetic Domains.  I don't think the M-H Curve is the same as the B-H Curve from the brief research I have done on this so far.

At 12 seconds in the video you can see the topic on M-H Curve in the presentation for the SKDB learning resources if you make the video full screen, http://www.youtube.com/watch?v=su3T7NFs85U

I posted this information in the Steorn's Patent and SKDB thread I recently created, http://www.overunity.com/index.php?topic=8763.msg227819#msg227819

I think Steorn is using Magnetic Recording Tape for their core materials.  I already posted a video of Sean talking about "tape price" and the user vorrex corrected me and thought Sean was referring to a magnetic effect noticed in old fashioned "tape drives", http://www.overunity.com/index.php?topic=8411.msg225528#msg225528 . 

The M-H curve points in the direction of magnetic recording tape.  Neptune threw the idea about using recording tape a few pages back, http://www.overunity.com/index.php?topic=8411.msg227714#msg227714

Look at the graphs I posted earlier and take note of the low flux measured in Webers in Fig. 15 .  This also may suggest the core material is a magnetic recording tape, http://www.overunity.com/index.php?topic=8411.msg227801#msg227801

Here's a good reference on recording tape, http://www.tonmeister.ca/main/textbook/node417.html   Please read all of the subsections on that web page.  It really puts everything together nicely.  The gap between the dual magnets will act as the gap in the record/playback head.  This is so brilliant.

Metglas cores are tape wound.

Metglas cores are tape wound.

So is Finemet and a lot of other cores.  Just because metglas cores are tape wound doesn't mean it's the right material.  The only reason why you want it to be a metglas core is because you have previous designs on a magnetic switch built around the metglas core.  This is the reason why you wanted everyone to verify the date stamps on your designs and is the reason why you're pushing metglas so hard.
