> Instead of thinking of mechanical objects as primary and electromagnetic stresses as secondary consequences, you must think of the electromagnetic field as primary and mechanical forces as secondary. Feynman explained this nicely. He said essentially, you ask me to explain what is electmagnetism. Is it like two hands pushing on other? Well, if it is, then what is "pushing"? Pushing is just the result of electomagnetism in your hands! It is impossible explain electromagnetism to you in terms of anything simpler that you already understand. It is a fundamental force.
