Self-Runner NS Coil Pulse Motor Live Video Stream. It's been going for months!

Is this what you are saying here?

No. Im saying the standard galvanized or un-galvanized iron wire being used will not work indefinitely unless there is a reverse polarity applied to it stopping the permanent magnetization. In my mind even with reverse polarity, the higher carbon content will not give you the higher magnetic field intensity on collapse as with low carbon iron which would diminish the amount of current in the copper. From what Ive read 1018 low carbon steel has been the most common and is probably what Ns had in his bolt and possibly his wire. Lasers core is even superior to that. Something I question is how much reverse current compared to forward current is in the copper when its magnetic field collapses from its larger reverse voltage spike? 
Standard Ac coils and devices use added silicone steel laminated cores for its superior collapse and intensity. But even the lamination's are high iron/low carbon with silicone added. That itself would influence me to use no less than 1018 steel for the core and the wire.

My 3rd coil is same as 2nd coil except I used Distilled Water:
one layer coil: a layer of cotton on core, one layer gal. steel wire, a layer of cotton, one layer bare copper wire, a layer of cotton.
I wrapped the coil in plastic immediately after removing from water to keep it wet.

readings:
  .100V   3:12PM  D1  1mA    9/26/2010
  .015V   8:22PM  D1 .5mA    Very little magnetic field - compass just moves 1/4 turn.
  .015V  12:05AM  D1 .5mA 
  .015V   7:23AM  D2 .5mA

I took the plastic off, water dripped off of the coil and the readings jumped to these.
  .480V   7:32AM  D2 2.6mA
  .500V  11:07AM  D3 1.1mA   Added plastic back now.

Conclusion: the coil was too wet.  I needed to let it drip a while before wrapping in plastic.
Even these new readings are a lot lower than with tap water.
Still almost no magnetic activity against a compass with distilled water.

I think that what @lasersaber did was to wrap the wires side by side instead of one over the other.

I could be wrong though.

Yes he did but I don't have cotton insulated copper wire so I did it like this.
You'd have to look at my other posted test results to get the whole picture of what I'm doing.

This is my 3rd coil test where I'm testing distilled water vs 2nd coil tap water.

I'm testing distilled water vs 2nd coil tap water.

Tap water is not pure water - it has impurities, chlorine, etc in it.
The impurities conduct the electricity, not the water.

Pure (distilled) water is a very poor conductor as these impurities have been removed.
The number of molecules of water that are dissociated is practically negligible, making the distilled water a weak electrons conductor.

Salt water is the most conductive.
When salt is added (NaCl) to the system, the conductivity of the system increases considerably.
The water not only dissolves the salt, as well as it dissociates the salt molecule.
The elementary sodium (Na) presents an excess electron and the chloride (Cl) has a strong affinity for electrons.
Consequently, after dissociation, the sodium loses an electron to the chloride, forming Cl- and Na+ ions.
The presence of these ions increases the conductivity of the water considerably.
The positive ions (Na+) migrate to the negative electrode (linked to the pole - of the battery)
and the negatives (Cl-) migrate to the positive electrodes (linked to the pole + of the pile).
The conductivity of the aqueous solution water/salt is proportional to the ions concentration in the solution.
