Partnered Output Coils - Free Energy

[MarkE]

  Reliable evidence is what it's all about. Yes, I do have an issue with the "reliable part", and the who, as well.
As some of the so called "evidence", is produced by unreliable people, with dishonest motives. Or are just plain lies, or purposeful disinformation, all made up for a secret, hidden, or unknown objective.
The ignorant or naive part, I can understand.
 
  Mark.E: We are on the same side, the side the truth is on.

  How many more pages are going to be devoted to an unknown, and unverifiable device. Which is Not free energy, and is also not much more comparatively efficient, as is being shown?
  1500 pages, or so, like the Kapanadze thread discussions. 10 years later. Still No cigar.

The bucking coils aspect of the thread is dead.  No reliable evidence of EMJ's claims was ever offered.

Tinman is not making an OU claim.  He has presented a set of curious appearing demonstrations.  For reasons of his own he does not care to disclose more than he promised.  If anyone thinks that he is really onto OU, they can go get used appliance motors of their own.  Odds are not with them.

Here is something for you to think about:  What if you could get the same useful result for a lot less money and/or a lot less input energy than you do now?  Wouldn't the difference between what you were able to get before be effectively free on an on-going basis?  I contend that energy efficiency is the "real" free energy that we can really get.

My Arduino based metal detector easily responds to a piece of ferrite about the size of my little finger (a broken bit of flyback core), at 10 cm distance from its _air core_ sense coil.

The way it accomplishes this amazing feat is simple. The circuitry, powered from the 5V regulated bus of the Arduino, oscillates the sense coil at around 120 kHz or so. The frequency of the oscillation is very sensitive to the inductance of the coil. Duh. The proximity of the ferrite changes the inductance of the air core coil, even from some distance away. The Arduino is used to monitor the frequency with high accuracy, taking a sample for a "null reference" , and when the frequency changes due to the change in inductance of the coil due to the presence of ferrite or metal, the Arduino produces an output click at a rate that is proportional to the change in frequency from the reference value.

The conclusion is that air core coils do change inductance measurably in the presence of materials of high permeability.

Imagine if people had lost coins or jewelry with ferrous metal nearby.  Why we could use such a device to find those lost items!

It works quite well with aluminum and silver too. I don't have any gold so I haven't tested that. It loves aluminum beercans!

That's probably due to eddy currents.

Hi TinselKoala,

I agree that air core coils also change their inductance when ferromagnetic materials are placed near to them.

Can we compare the effect of a ferromagnetic piece on an oscillator coil working at 120 kHz to a coil working at 1 kHz, 100 Hz or 10 Hz ? It all depends on what change takes place percentage wise in the L inductance of the coil, no?

An L meter could easily tell this or further measurements on the coil as tinman wrote to perform that.
