Nice pix with arrows. The corkscrew.gif, second to the bottom is your best best for driving the coil. It creates a shifting and rocking field smoothly in the huge field we are in. The Hamel disk exhibits the same field creation. In the coils each pulse can create the kick but it seems that overall you want the fields to move effortlessly maintaining an axis wobble similar to planet earths. I have posted this previously about the Hamel disk generating the balanced magnetic wobble mechanically. We, on the other hand, are set out to achieve that in solid state. I should note that the 1st 3 Hamel disks were self destructing being they were uncontrolled operation.

Also, what is the formula to determine the wavelength of the core? would it be the same as a standard antenna?

Its' very simular in that we need to know the velocity of the wave.  Antennas deal with waves in space, hence the speed is 'C=3x10^8'.  However here we're dealing with TE waves which propagate INSIDE the material or core of the toroid.   Note that the toroid can support many wavelengths (or frequencies),  I don't have an exact formula but I would give you this.

(time for wave travel once around loop) = (circumference) / (speed of wave in medium).
(speed of wave in medium) = (3x10^8) / 70   (m/s)  its approximate for iron medium
(frequency) = K / (time for wave travel once around the loop), where 'K' can be 1,2,...,1/2,1/4,1/8....

I should say that other 'K' values will give patterns which are not stationary on the toroid but will "ROTATE" this is another area to explore.

EMdevice,

Interesting.....

Well from what you mention then it seems that experiementation with a non-standard K value would be the requirement to get a rotating field in the core. A wavelength that is not an even number that is, maybe a third??

I would hypothisize then that using a solid wire (iron) for the core using an odd wavelength torrid size to the driving frequency and flanking this core with stranded copper coils (top and bottom, in a stacked arrangement if you will) to collect the power (having the magnetic lines of flux cut the wire while rotating) would give us our power output possibly.

Your thoughts?

ive been trying to upload part 4 of the experimental videos for two days almost.
but the site keeps sending an errorr message.

so i throw it on google.

enjoy

Hi Marco,
what did oyu do in the last 2 parts of the video ?
Is this a one wire signal that you drive the control with ?
Where is the bright shining lamp connected to ?
To the green wire (iron wire ?) coil ?

Does the lamp light up,
when you just apply to one control coil a square wave
with just one pin at it ?
Or do you drive the copper control coils
around it with a function generator and with both pins
of the control coil connected ?
What frequency and what waveforms do you drive it with ?

Many thanks.
Just trying to catch up of your latest videos..

Regards, Stefan.
P.S: Where the ruler (lineal) connected to ?
Is it out of metal ?
Please speak in your videos, what you are doing, so
one knows, what you are doing.
Many thanks.

hi
i did explain this all a while back.
in the last two parts i show that when you place a piece of aluminium paper on top of the coil and on the bottom it differs when you hit it with the sense wire.
the piece of aluminium isnt connected to anything.

the bulb is an indicator to show what happens when my hand is in the field.
its connected to the output of the amp.
the bulb lits up as the amp gets a signal from the sense wire.

the last part is to show that the coils were testing are grounded.
keep that in mind when you use generators/mosfet/tip/555/whatever.(onto ac line)

stevens coils ar not grounded so this differs a lot.
thats why one segment lits and the other not.

i drive the input with the output and between is a variabel capacitive field.
so you have a field around the coil comming from the amp.
nothing happens but when you take the input into the "output field" it picks up.

i can hardly type enlish so im not really into talking in the videos but im doing the best i can.
sorry for that i will try to use more explenation images between.

now im in a hurry gotta test some stuff.

marco

Ahh, I see,
you created just a feedback loop with the 2 coils.
But you always used the amplifier in between, so the power
for the bulb comes from the amplifier... Okay, I see..


Have you already posted any scope shots of
your iron wire output coil, if you drive one copper control coil around it
with square waves ?

Did I miss that ?

Did you also get any kicks superimposing in the iron output coil then ?

Many thanks.

P.S. Marco,
if you speak in Netherland?s language in your video it would
also be okay, or if you try in German, if you can, I can translate
that into english text over here..

Or just put a few drawings into your videos, what you are doing
or just a Powerpoint presentation. ( This could be easily
converted to AVI movie)

Many thanks for your great experimental effort !
