Electron Flow - Electromagnetism - why? My theory

[Scorpile]

I have my theory of some "well known facts".

1st fact is that circuits works like a flow of electrons from negative pole to positive pole because of the potential difference betwen the poles.

2nd fact is that this flow generates an electromagnetic field arround the wire.  But the shape of this electromagnetic field is different to the shape of magnet's magnetic field.

Let's see the drawing i made.


What i think is happening when you close the circuit:

1-The excess electrons from the negative pole of the battery start to move to the positive side through copper wire, charging the copper (in this case) atoms negatively. 

- Or -

2-The absence of electrons from the positive side start pulling electrons from copper atoms, in a "chain way", charging the copper atoms positively.

In both cases the electrons are moving arround the "round like" array of atoms who conform the wire, which explains why the electromagnetic field is arround the wire, and the wire being "changed" to be positive charged or negative charged explains why the flux generates an electromagnetic field.

Both circunstances explain well the 2 "well known" facts, but then we have the problem to know if the circuit is pulling electrons, charging copper atoms negatively, or pushing electrons, charging copper atoms positively.

If we take the 2nd explanation, then we explain also, why everybody says that current is flowing from positive pole to negative pole but electrons flow from negative pole to positive pole.

Is this already solved? I'm correct? I'm wrong? Anybody can help or have information?
