The Master Of Magnetics "Steven Mark"

So, what resonant frequency should we design out resonant circuits to:

Schumann Resonance: 7.83Hz
--- wavelength of  38287670 meters 38287km!

OR

Magnetic Field Resonance: 173.9KHz
--- wavelength of 1723.93593 meters - 1/4 wavelength of 861.967965
--- wavelength of 5655.95777 feet - 1/4 wavelength of 1413.9894425
--- wavelength of 67871.49324 inches - 1/4 wavelength 16967.87331

On a tesla secondary the wirelength used is a quarter wavelength. I don't know whether this is strictly relevant but I've given the wavelengths above incase they ring any bells with numbers that are the same or very near, that you've seen else where or in other devices.

By the way I found this website to convert between units rather than plugging numbers into a calculator:
http://www.1728.com/freqwave.htm

Given that a magnetic field from a magnet seemed to set the coils in motion. I'm assuming that the coils are tuned to the Magnetic Field Resonance and that the 7.8Hz vibration that Steven once mentioned is a side effect of this tuning.

Diameters of Steven Marks coil - are 5 inches (from Engineers report)
2.5 inches - mentioned by Steven on video.
15 inches - my guess by looking at the video.

As Steven Mark said the frequency is related to the circumference of the TPU (and therefore the diameter).
Although I'm used to dealing in meters/centimeter I think our measurement units should be in feet and inches.

I'm going to try and come up with some calcs for the 2.5 inch version... I'm assuming this will need less wire...

Well, it is not the flux density at work, but the magnetic vector potential A .
The flux density is always just the output of a vectorpotential change  dA/dt .

So this is always overseen in magnetic circuits.
This is why it is much more intelligent to try to design magnetic circuits
from looking at the magnetic vector potential A, which is perpendicular to
flux density B !

You can NOT explain a transformer logically with the fluxdensity change dB/dt
but you can explain it very well with the dA/dt change !

Hi Hartiberlin,
Not familiar with the term magnetic vector potential A - is this the Electric Field component of an electromagnetic wave ? or related by some formula ?

[hartiberlin]

Hmm, it is the curl of magnetic flux density B.
But it can be seen as a perpendicular circle around the
flux density circle .
So the electron flow in a wire is really only caused by the A field,
cause it directly propells the electrons.
( The electrons flow in the same direction the A-Field curls around
the magnetic flux line...)
The magnetic field line
around a conductor is only a side effect !
So in a transformer with a circular iron core , where the
B-field from the primary is totally inside the core, the scondary coil
just gets its power from the changing A-field and  not from the
changing B-field.

What would be interesting to study would be a transformer,
that has a DC current in its primary coil, but the core diameter is
changing ! This will also induce power in the secondary coil,
as the A-Field is changing !
or build 2 iron cores in each other, one with a bigger diameter
and have on each core a primary winding.
Then switch the primary current from the bigger diameter core coil to the
smaller diameter core coil and have a secondary coil going through
both cores.
Thus you will change the diameter electronically and thus have a changing
diameter core... This will induce current inside the secondary coil....but I don?t know,
if this have a Lentz effect on the power source....
so ifyou draw power from the secondary it might not be reflected back to the 2 switched
primary coils...

As Steven Mark said the frequency is related to the circumference of the TPU (and therefore the diameter).

I think I've found something that is either amazingly coincidental or extremely relevant...

Given that 'pi' 3.1415926535897932384626433832795 etc is used in coil calcs and in calculating circumference from the diameter I decided to divide the wavelengths by 'pi' to see what I would get. I choose feet because this is the unit of measurement that Steven Mark used.

Guess what: 5655.95777 / 3.1415926535897932384626433832795 = 1800.3472740290264967375540913472

What are the chances that dividing by 'pi' is going to be 1800 and a decimal and not 1801 and a decimal but 1800 ? But also that the Steven Mark diameters of 2.5, 5 and 15 are exactly divisible into 1800 ie. factors.

And similarly for the quarter wavelength 1413.9894425 / 3.1415926535897932384626433832795 =
450.08681850725662418438852283681

And 450 is also exactly divisible by 2.5, 5 and 15.

Working backward:

1800 x 3.1415926535897932384626433832795 = 5654.8667764616278292327580899031feet

Wavelength of 5654.86677feet = Frequency of   173.933551kHz

This has got to be relevant ? Or is it a mathematical oddity ?

[hartiberlin]

Hmm, yes, seems interesting...
Maybe he is just pulsing his iron wire coil with around 180 Khz,
where the Barkhausen noise occurs and this way with one single pulse
he can get several pulses from the barkhausen domain jumps in his iron wire
and if he feeds these back in a collector coil wound around the iron coil, he can have a positive
feedback loop, so this thing gets itsself to oscillate ?
