Group: Administrator Hero Member Posts: 3960	MIB's been at the diagram with a rubber This is where a versatile construction method could be handy, if the coils are made removable then the core could be slipped out and magnets added in place, or new coils tried. I am trying to knock up some software to do the maths on the coils, turns, wire gauge, length, diameter etc so i can see the inductance and wire length etc. Whats the correct inductance formula for a iron core solenoid coil, u=200 for iron, so far i have found 3 slightly different formula.

Group: Tinkerer Hero Member Posts: 3948 tExB=qr	OK, after stewing over the patent and diagram, here are my conclusions: 1. compound helices are what is shown in the diagram with one coil over the other 2. simple helix is just a single coil, he says two can be used with the poles connected together (he doesn't say crossed polarity) The simple coils have to very very large. 3. main circuit D is the circuit of the coils, this get's the rheostat, but maintains the perpetual action of the coils (yeah, that's hard to believe...) 4. the starting circuit or action is just an inductive pulse to one of the coils

Group: Administrator Hero Member Posts: 3960	Brilliant Grumpy That's exactly what i think. The rheostat is simple to grasp, the initial spark from the battery starts oscillation, this means we are not picking up any ambient signals, but i suppose it could be interacting with the earth's field. Once started the battery can be removed, if the device needs to be stopped, he allows a residual amount of current to recirculate in the coils to allow them to keep functioning but on a very low level, this almost means that when you draw a large amount power the device provides it alone and runs hotter. It sounds as if it truly defeats lenz law when in operation, although it maybe stealing energy from a magnet as well. It has been known that some early generators used the earth to start stator coils. it maybe possible that hendershot also used the same process but instead used the earths field to start it. The thing that keeps me going on this bazaar Cook coil is that Tesla used 2 iron rods in his device, i wonder if Tesla had any patents that use very large cores and amounts of fine wire. It is also possible the effect is increased by winding in Tesla bifilar method. OK i am pretty sure this is the Inductance formula i want ------------------------ e67776bf588dd43b018cfd9529488972.png (0.6 kB, 95x43 - viewed 2566 times.)

Group: Administrator Hero Member Posts: 3960	Whats this mean Quote Long Range Order in Ferromagnets The long range order which creates magnetic domains in ferromagnetic materials arises from a quantum mechanical interaction at the atomic level. This interaction is remarkable in that it locks the magnetic moments of neighboring atoms into a rigid parallel order over a large number of atoms in spite of the thermal agitation which tends to randomize any atomic-level order. Sizes of domains range from a 0.1 mm to a few mm. When an external magnetic field is applied, the domains already aligned in the direction of this field grow at the expense of their neighbors. If all the spins were aligned in a piece of iron, the field would be about 2.1 Tesla. A magnetic field of about 1 T can be produced in annealed iron with an external field of about 0.0002 T, a multiplication of the external field by a factor of 5000! For a given ferromagnetic material the long range order abruptly disappears at a certain temperature which is called the Curie temperature for the material. The Curie temperature of iron is about 1043 K. PS i have the inductance calculations sorted now

This sounds just like the Leedskalnin PMH or a variation of it and the action almost identical.... coincidence?. I would imagine they were doing exactly the same thing, damn copy cats.

Hero Member Posts: 805	A negative inductance that can not be disabled at will is not going to produce OU when averaged over integer cycles of the current waveform. To visualize this consider a triangular waveform of current flowing through such a negative inductance. If the curent does not increase there is no voltage across the inductor but as the current ramps up this inductor creates or develops a voltage across it's terminals that aids the current, unlike a normal inductor that opposes the current change. Therefore, the current flows out of the positive terminal which means it is delivering power and energy, not absorbing it as a normal inductor does and putting that energy in the magnetic field. So far so good, this first rampup of the current waveform is an OU event, but here comes the ramp down part of the cycle. As the current begins to decreas, but still flows in the same direction, the negative inductance switches it's terminal polarity and now opposes the current, and thus absorbing energy from it. So, half a cycle is OU, the other is not, and each integer cycle the energy balance is zero. That's why I said that unless we can disable the negative inductor at will it won't help us. Preferably we want negative inductance for the first half cycle and positive inductance for the second half of the cycle. I'll leave you with this thought, A regular inductor absorbs energy then gives it back, but a negative inductor first gives energy than takes it back, the difference between a BANK and a CREDIT CARD EM

Group: Administrator Hero Member Posts: 3960	It has occurred to me wire length is everything. I have come to the conclusion there is no magic frequency of operation, It was once said SM trims his wire length, Don Smith aimed to have wire length of 1/4 operating frequency for feeding back energy, the Cook patent reads as if the primary and Secondary should be the same length even though 1 wire is thick and one is thin. So if there's no magic frequency of operation then it might be matching wire length that's important. How do you wind 2 large coils of wire and expect them to be the same length. A process is needed to test each coil and then determine how much needs trimming, so how would i do this. Is the process as simple as grounding one end of the coil to be trimmed, then exciting the coil with another coil running at the frequency that's wanted and trimming the end of the coil under test until the scoped waveform is zero, i imagine the signal generator can be adjusted and the scoped voltage monitored to see how far off i am.

Hero Member Posts: 805	You might be right, wire length is critical for any traveling wave type of resonance/antenna performance, so that standing waves can be created, thus resonance accomplished. Moreover, length could play a different role, as a delay line. In a feedback system, we need gain >1, and in phase feedback, or positive feedback. If either one is off (based on gain and phase margin of course) it won't work. But that's dynamics. In statics, if the wire were to produce the dc voltage per length, and really strengthen rapidly beyond a certain point, then length would be very critical. How much length are you shooting for? I'm shooting for 1000 turns on a 12" long coil. Here's another idea, make a sliding contact, and you can adjust the length easily. EM « Last Edit: 2013-01-20, 00:46:11 by EMdevices »

Group: Administrator Hero Member Posts: 3960	Hi EM Cook was clear that 2 foot core and 2 inch diameter is used or bigger in his device, if i get to the point where i can build then i will try this size. I've not yet worked out my turns or wire length, soon, i think he matches wire length, his primary coil B uses thin wire and goes on the core first for good reason. He does use 2 rings at each end of the primary & secondary, i suppose these could be adjusted for positional tuning, at first i thought these were complete rings, which would in effect be a shorted turn, but it is possible to see a slit up one side to stop the shorted turn.

Hero Member Posts: 805	If I build a coil with those dimensions I think I'll do very well where I'm at. I just measured a strong signal @ 60 Hz, and nothing is turned on in the house, but we live close to a high power line, maybe 1/4 mile. I get 10 volts p-p when I touch the probe. OMG, Just hooked up my big aerial coil and i get an unbelievably huge signal at 7.1428 Hz! Is this the Schumann's resonance? I get almost 2 volts p-p which is unbelievable! « Last Edit: 2013-01-20, 17:16:24 by EMdevices »

Hero Member Posts: 805	I rushed to the garage to unpack my electronics but I can't find one box with all my discrete components, we just moved so most of my stuff is still in boxes. The other day I just happened to stumble on the box with the scope so that's why I'm experimenting again. I love that scope! I think I'm going to step up the voltage with a transformer and see if I can light a LED with it, once I find my components. I sure hope the strong signal returns tomorrow in the morning or today in the evening. I tell you, this was a freaking coincidence, just happened to put it all together at the right time to observe it. EM

Group: Guest	So we need to look at: https://www.google.com/patents/US119825 Correct? Seems like I mused this once before. Big, long inductors that I wasn't too confident I could actually wind. What would be nice to know is its principal of operation and why you cannot just connect two normal transformers together and get the same effect. The only thing I can think of is the interaction of the two open cores somehow magnetically interfere with each other. This interference must somehow be additive.
