Electronics Question:

Flow of electrons is just what it says - electrons flow down a wire that is what current, is. Good conductors like copper and silver and aluminum have free electrons in their outer shells, and they jump from atom to atom down a wire. It is somewhat similar to water flowing down a pipe.

It's kind of amazing that you can force this to happen with a battery or a magnet, and that you can transfer energy this way, but that's what it does.
