Mark E
you have an agenda which is rock solid ,however my position
from a point of such ignorance should embolden your betting portfolio.

Lets not be boring.....

come on put some meat on the table.....

this was your idea not mine ?


crickets chirping.....

HHMM is it 12 hours and no response??
I guess you got your whole crew ,,,,,er colleagues working on this one??

very very untypical of your Mark E .......

   Most conductors have defective atoms.      Atoms don't like unpaired electrons in the valence shell and would normally share this electron in a covalent bond or boot it to form an ionic bond.   In the case of metals they really aren't atomic but more of a plasma.  The electrons are arranged outside the influence of the nucleus and form a plasma where the bulk of the electrons are in electrical relativity to the bulk of the nuclei.  So the electron cloud or liquid is easily influenced by electric fields.  Electric fields accelerate electrons.  The distribution of the nuclei in relation to the electron liquid and the amount of heat influence the resistance of the conductor as well as the number of electrons in the liquid.  Electron a moving on a switch contact towards the end of a conductor will have an electric field moving along with it.   When the electron laden contact gets close enough to the other contact it will move electrons in the wire connected to the other contact.   They don't even have to touch.   This is how you couple two ac circuits.  You use the electric field to push electrons out of one plate.  You don't need a closed circuit.

    I'm fascinated by the circular patterns which occur with the Ferrocell  pictures.
Just wondered if there was a simple explanation.

I just found your post and will explain:

When light bombards certain metals, electrons are ejected. This is called the "photoelectric effect".
Iron isn't one of the best materials to create the effect, but Fe falls within this group.
The application of a strong magnetic field causes the electrons to follow the lowest potential of the field.
This is the 'ring' you refer to, and the same phenomenon can be seen using other methods such as plasmas or gasses.

That's the simple explanation.

The video you just posted on OUR is excellent.
The field has to be bi-directional, half the field is going in the opposite direction.
Turn the magnet 90 deg. so it runs in line with the wire.
Now rotate the magnet ,with flow in the wire , the wire should bounce up and down.
There has to be a point where the fields change.
What determines that I do not understand.
