If one were going to cut (iron) wire to (magnetic) wave length, what do you suppose the length of it would be?  I noticed on one of the posts, that a patent showed using a frequency of 21 mhz.  If we use this frequency, and go with a multiple of the wave length, I think that 11.73 feet would be a good ball park area to start.  (Formula is 984 / Freq. in mhz = length in feet) (If I remember correctly).

Has anyone else tried a particular length of iron wire?  Any successes or learned lessons on attempts?  Give your best guess as to what the length of wire should be to put us in the ball park...

Here is a Excel table to calculate with different frequencies.

Liberty,

my old "Tune in the World with Ham Radio" book says for a half-wave dipole length in feet = 468/f.  f is frequency in megahertz

That being the case, a quarter wave antenna at 21 mhz would be about 11.14 feet.

Here is a web page that calculates this for you.

It is:  http://www.csgnetwork.com/freqwavelengthcalc.html

12 ft iron wire 4 in form loose winding
and a mag wire secondary should give you the kicks
I will post scope shots of the kick

Hi Mike,
looking forward to see the scopeshots.
If I get some free time next week I will also try a few
iron wire coils with pulses and will see, if I get some
unusual kicks or some Barkhausen noise at least...

Hey Stefan,

try this out, a circuit I use to see the kicks

Hi Mike,
thanks for the picture diagramm.
what are the Relays exactly doing ?
Why use at all the NC ( not connected ?) pins of it ?

Do you just pulse the iron wire coil with 300 Volts DC ?

Do you use a bifilar iron coil, so no magnetic field inside the iron
wire coil or do you use it as a normal iron coil ?
What are you seeing on the scope ?
As you generate probably many sparks at the relay, it is
no wonder you are seeing kicks on the scope...
Better do it with transistor switching.
If you see with transistor or CMOS switching also multiple
"kicks", then you have something.

Hey Stefan,
 I use the NC normally closed contacts for two things:
1. To operate the relay coils, When the 9vdc is applied through the NC contacts the relay coils will be energized opening the  normally closed contacts which instantly cuts the 9vdc going to the relay coils which again closes the NC contacts.  This puts the relays into oscillation, at 9 volts the 12v relays will oscillate very fast. the armature will not travel far enough to close the normally open NO contacts this is why,
2. I use the NC contacts to switch the 300v from the caps to the iron wire bifilar windings. I use high voltage pulses from a Bedini motor energizer to charge the capacitors to 300v and maintain this charge on the caps.  The relays will all oscillate (4 total) at slightly diffrent frequencies the circuit I drew up is the primary circuit for one of the bifilar windings. The on and off times are fast since the relays oscillate at slightly diffrent frequencies.  The bifliar windings are pulsed at random frequencies and phases.
Hope this is not to confusing.

ps:This could all add up to alot of noise :o on the scope as you pointed out.  The scope shows alot of little spikes constantly, and very large spikes intermittently.I am still trying to get a picture of this signal on the Oscilloscope to post.

Mike

Hi Mike,
with this circuit you use you make much too many sparks and
you have the Newman effect also in your circuit, which is normally
good for energy production, but in this case it is bad to see some
multiple kicks, which should come from the magnetic field divergation
of the iron coil.
So you need to get just a single pulse onto the iron
coil , driven via a transistor or CMOS driver circuit and look out
for multiple pulses then from the iron coil. This can not be done with your circuit.

Stefan,

Check this out
 An odd oscillator configuration at http://www.electricstuff.co.uk/oddosc.html
One pulse makes many 
no iron wire though
