Natural Magnets: How do they work? I'd prefer a technical answer on a subatomic level.
Electromagnets: Say you have a copper wire hooked up to a negative terminal and on the other end of the wire a positive terminal. Due to a potential difference, electrons flow from the negative to the positive, but how does this induce magnetism?
