Main Question or Discussion Point
hey everyone, I have a questions, that is very general, and perhaps, silly... but why are coils so significant in terms of electricity and magnetic fields? why is it when you push a magnet through a coil, you get a charge, but not when you touch it to a straight copper pipe? Or when you see generators, they always use the coil form? What is it about a metal coil, that conducts better than any other shape?
