Do two electrons traveling in two unshielded "parallel" wires in "close

polarities are reveresed due to spin and right/left hand rules) that
cause attraction between both wires (therefore if very close the wires
would bend towards each other)??

Currents in opposite directions repel. Currents in the same direction
attract.


You mean magnetically of course, but either way the electric charge in
a current is always stronger (unless wire is a coil) and always
repelling.

Not at all. The attraction can easily be stronger than the repulsion.
This is a common demonstration.

You mean in a normal copper wire the magnetic force of a current is
stronger then the electric force????? ....?????

Depending on the current, yes, easily.


Then why doesn't current flow in a circuit due to the magnetic instead
of electric force (since electrons are never static inside a copper
atoms or wire)?


Because there is no driving magnetic field in a circuit, where there is
a driving electric field. Note that magnetic fields are created by
*moving* charge and only influence *moving* charges, and the direction

In atoms electrons are always moving (not static), thus a moving charge
and therefore a magnetic field.
Likewise a copper wire (copper) is atoms and should have moving charges
and a magnetic field otherwise are you saying that electrons oribiting
the nucleus of copper atoms don't have a magnetic field?

of the magnetic force is perpendicular to the direction of the charges
motion.

Please do not think that magnetic fields are just another force that
acts on charges in exactly the same way that electric fields do. They
are very different in key ways.


In space isn't the electrostatic charge stronger then the magnetic
force (then a magnet) why would it be different in copper wires?

I don't know where you got this impression.

which impression you're talking about? if the electrostatic charge
wasn't bigger (not really static since electrons are always in orbital
motion) then the magnetic force then electrons would be attracted
instead of always repulsed by each other?









Can the magnetic attraction of these fields in the wire be stronger
then the electron's repulsive charge (if so what causes the magnetic
field to get larger)?
