This is a follow up on Geo Stress , and must be taken into account, as the Planetary body is subject to more than one type of stress. The following will show the added physical stress that makes the whole, and must be taken into account to allow a reasonable evaluation of a general mapping attempt.

The following animations and pictures , show the generated electrical field , as the gravity strings hold it in place, also envision and understand that the "Gravity Strings" I refer to , is the gross attraction cutting across the planetary body at right angles , from the "primary" it orbits (Solar , or massive planet). I don't want to get too far into the intricate mechanics involved, but rather show a visual to allow both researcher and novice , where each can extrapolate an understanding of what I am aiming at , according to their interest.

There are factors that have to be taken into account, such as our own Earth is not spinning at a perfect right angle to the Sun, causing the Liquid core to attempt to compensate, again this is under the law of Centrifugal Mechanics, it attempts to correct itself , apart from the Mantle, an interesting phenomenon , and I personally wonder if it corrects the unbalance of incorrect spin of the whole, permitting less Geo Disturbances, or creating more , very interesting.

The above animation is grossly exaggerated, but shows the error correction attempt, not counting the offset, however it shows that at times there is more generated electrical energy. And picture No:1 shows the fields and generated poles , colored gray from the molten core.

The angle of the gravity string agitating the molecules across the Planet must always be at right angles to the Magnetic Poles, IF it isn't, then the liquid core is causing it, attempting to compensate for the Mantle being out of orbital sync , again such as our own Earth.

I placed the No :2 picture at 180 degrees to the animation for a different perspective, and I add , the liquid core logically assures more right angle generation, as it would seem to generate more electrical energy across its axis .

As you can see the outer area moves through the Gravity string in the opposite direction than the inner area , creating the polarized electrical energy, and at a constant rate, that causes the magnetic poles to generate at a constant rate at right angles to the rotation. There are other factors involved, as the electrical flow will seek the least resistance to terminate, that factor would depend on the material it had to flow through, and likely would vary some , in seeking to complete it's cycle, as the electrical energy would be DC , it would be difficult to detect. Everyone should attempt to think of ways to tap this resource, as it would be inexhaustible, perhaps a cable half way around the world?

I suspect lines of Gravitational force acts like lines of magnetics , and are separated by a small amount, when it cuts across the whole of the planet , generating molecular agitated electrical force,there are separations , or valleys in the field,and it can be read as a frequency, or a way to read the distance between the lines that occur running through the planet, this would allow maximum generation of electrical force. The more force is generated, the wider the lines (pushed farther apart), and the lower the frequency read, and the greater the effect, also this must have a settling effect, or a compacting of the surface material over time. In any case, it is speculative that the Gravity lines separate, but physics demand a separation of either the electrical or Gravity lines, little difference for our purposes, rather a way of measuring the distance between them , as the frequency would give the distance between them, this is the Song of the Earth, and a Key to determining actual generational power available, good to know later when we are to the point where technology can draw on it for alternative power purposes , when we go elsewhere.

Simple logic shows Gravity is minimally , or not at all effected by Magnetic fields, at least not any that I am aware of, until it is converted by some means into another type of energy, lets call the types associated with macro gravity fields Alpha polarity , if they don't effect each other directly, and a Beta effect , when there is reactional occurrences, as with electrical flow.

Energy converts to other types of energy at right angles, no matter if it's electrical or Gravity, or mass running into other mass at high speeds. The Generational effect of electrical energy caused by lines of Gravitational force agitating the basic molecular structure can be seen by the Magnetic poles, as Magnetism is a direct effect of electrical activity, electrical activity is the direct effect of wholesale agitation over a large area. There is no Eureka syndrome here,just simple logic using available physical known Laws. Perhaps no one looked at it this way before is all, someone had to come around to seeing it sooner or later , as we are nearing the jumping off point to serious Space Exploration, and this simple understanding of Macro effects is needed. I had a difficult time understanding just how magnetized rock (Load Stones ) could be piled up enough to generate the Magnetic fields we measure, it isn't/can't.

Addendum #2 I see that one or more of you have read my material and acted on it, good , I want to stress that there are more options open than determining conductivity of an object, the "Song" like our base frequency of the Earth, is operating in all objects that produce a magnetic field in Free Space, the larger the reaction , the stronger the magnetic field , this is a multipart action , showing the Gravity interaction, the conductivity of the body, such as water, but the "Song" determines the spacing of the ridges in the field , demanded by physics where energy is generated, this can be a generalizational method to determine the actual Gravity present on that object, simply by the frequency, hope this helps, and it sure puts another piece in the information to analyze a nearby object for Teutonic activity.
