"Cold current" may be caused by novel magnetic subatomic interaction

[lancaIV]

Thanks a lot for the link about the #1,3,7,8,10 context !

I thought that the Fleming -Left-hand-rule would be a geral rule,
valid for wire,circuit,transformer :

What do you think is wrong with this rule ?http://www4.ncsu.edu/~rwchabay/emimovies/

I believe spin has a lot to do with this.

Current-induced spin polarization ....

   I would think that the temperature of a conductor carrying a current would be determined by the ratio of unbound electrons to bound electrons.   Your coldest currents would occur in a confined electron gas.   Even then this gas will become heated as electrons changing velocity will produce synchrotron radiation, which will irradiate the gas,  and increase the random motion of the electrons within the gas.

There are two ideas in the previous post that will lead to confusion.

1.  There is only a right hand rule, there is no left hand rule.  It doesn't matter if it's conventional current or electron current, you still point your thumb in the direction of the conventional current to see the direction for the magnetic field lines.

Of course, convention says point your thumb in the direction of conventional current. The point is that you can think of electron current this way, but doing so requires you to use the left hand. I like to think of the actual particle which moves in the wire (the negatively charged electron current), so I like using a "left-hand rule" for this.

2.  The fingers don't represent the "circular orientation of the north pole."  That's a concept that doesn't make sense, there is no orientation for a north pole or a south pole when you look at the magnetic field around a wire.  The magnetic field around a wire is the classic example illustrating how there is no true north pole or south pole.  There are just magnetic field lines that have a direction and travel in closed loops.

Yes, there is no literal "north" or "south" position of the magnetic field around the wire, but there is a "north" or "south" direction of the magnetic field around the wire, which can be verified by a compass. You can assume that a pole refers to a position on a magnet, or you can assume pole refers to direction. Since the arrowhead is placed at the north end of a magnet, the arrowhead of a vector indicates the "direction of the magnetic field", which inside the magnet runs from the south to the north pole, and outside the magnet it runs from just outside the north pole to just outside the south pole. We can assume the local arrowheads are "inside virtual point magnets" distributed throughout space. The orientation of the "north pole" therefore means orientation of these "virtual point magnets" that make up the vector field representation of the magnetic field.
