Since, I need to get this out of my system....I would think that if, electrons were coming out of (from within each respective element) a copper coil or an iron core that both would begin to change into another element. Since, I do not see this happening...it still seems to me that this electro-magnet combo is a gatherer and channeler of electrons. Other examples or things to consider are static electricity and magnetic field lines that a bar magnet produces which attract or repel iron filings. Every electric current produces a magnetic field also. IMO...it's all related and it all makes sense. It's all about accurately figuring it out and/or just flat out using it.
