When Manufacturing Electricity Where Do The Electrons Come From?

Electrons are a significant part of every atom. Electrons are everywhere in the environment. When electrons are flowing through a conductor is results in the generation of electricity. So, to generate electricity, all you need is a metal wire which is a conductor and a Catalyst or means to start the electrons flowing.

Suppose, you are generating electricity by moving a magnet around a conductor, when the magnetic field is in motion relative to a copper wire, it will trigger the flow of electrons in the wire which will create electricity. In power plants, electricity is created by using large quantities of copper wiring wrapped around a shaft which is called an armature. The armature spins inside very large magnets at very high speeds.

This answers what electrons do, but not where they come from. Are they removed from the metal (wire)? Why don't wires shrink in a generator after years of producing electricity? Do they come from the magnet? Do the magnets in a generator shrink or lose their strength after years of producing electricity? If they come from the wires or the magnets are they somehow "replaced" after they've produced energy?

The electrons are in the copper wires . .they are there to begin with . . The magnet only shoves them in a direction . . As electrons move out of the copper wire into a cable at one end . . They are replaced by electrons moving in from a cable on the other end . . Its a big loop of moving electrons . . Each pushing the next one along . . . If there is no loop . . There is no current.  Since electrons leaving would cause a positive charge which would basically pull them back before they even left.
