The animated diagram below shows what happens when the two ends of a battery are connected with copper wire. The negatively charged electron nearest the positively charged battery is drawn into the battery. This creates a positively charged atom (called an ion) which then in turn attracts the nearest negatively charged electron.
Here, an electric current in the copper wire is conducted through the magnetic field around the magnets. This causes a force to arise, which pushes on the copper wire and causes it to move. You have just built a machine that can make something move with the help of an electric current - an electric motor.
The electricity that is conducted through copper wires in your home consists of moving electrons. The protons and neutrons of the copper atoms do not move.The actual progression of the individual electrons in a given direction through the wire is quite slow. It is because the free electrons are already spread through the wire.
As an electron leaves the atom and is replaced with another electron, each atom changes from a neutral charge to a positive charge and back again. This continues on down the wire. What is happening inside a copper wire when electricity flows through it. How the atoms in the wire change charge and transfer electrons between them.
The magnets have been carefully aligned so the force on both magnets points in the same direction, and the result is that the magnets and battery move. But as they move, the magnetic field moves with them and you get a constant motion.
Remove the copper wire when not in use, otherwise it may become hot and cause a fire. Use the pliers to shape the copper wire as shown. Attach the magnets to the negative terminal of the battery. Balance the copper wire on the positive terminal of the battery. Be sure the wire ends are in contact with the magnets but not with each other. Voila!
How to Build a Simple Electromagnetic Train
(Just hold the magnets so that they push each other away, then stick the battery in between.) Step 2: Make your coils. The coils need to be wrapped pretty closely around the train. I found that wrapping the copper wire around a AA battery made nice even coils that were just the right size for the AAA battery plus the magnets. Once you cut the ...

In a circuit, does a battery create electrons which it ''injects'' into ...
If no, then does that mean that the battery looses power because the copper wire has run out of free electrons? Sort of - while you can''t create an electron, you can free one by a chemical process, which is exactly what happens in the oxidation and reduction processes at the battery terminals.

Does electricity flow on the surface of a wire or in the interior?
In this frame, there is a radial electric field outside the wire, which does not effect the electons, but does attract or repel charged particles outside the wire. But in a copper wire with typical currents, the electrons are extremely nonrelativistic ($beta ll 1$), so the net negative bulk charge and positive surface charge are extremely tiny.
