To Julio Friedman — with all due respect to your education — if you were taught that electrons are “realized” by passing a wire through a magnetic field to develop electricity — they lied to you - and no well researched text book will make that statement - so I didn’t take the time to continue.

The fact is that there are four Atomic Elements that are considered to be “natural conductive elements” that have a single, odd numbered electron in each atom’s outermost electron ring - named the “valence ring”- so the single electron is named the “valence electron” — and it is the single electron that is effected to move - when influenced by a voltage - such as when a wire is moved through the magnetic field you spoke of.

The four naturally conductive elements are Gold; Silver, Copper, and Aluminum.

There are more Atomic Elements that also have a single electron in their valence ring but are not considered natural conductors.

I also highly suggest that you get a copy of the textbook “…Electricity One-Seven…” edited by Mr. Harry Mileaf.

It is written from the viewpoint of explaining “electricity” rather that just starting with “Electronics Engineering”.

It will verify my statements above - and clarify a lot more that you should know.
