Now if you take a magnet and move it back and forth across a coil of conducting material you will generate what is called Voltage. This voltage is north and south pole magnets which must find there way back to the opposite poles. When a path to ground is provided this is what happens,but you don't actually have one current, there are two in opposite directions consisting of north pole magnets and south pole magnets.




Can you explain then the Lenz Law? Or why only conductors can flow a current? The relation between electrical and magnetic fields? The second Maxwell Equation (div B = 0)?



If the north and south magnets are forced in significant quantity within a tight space it will create heat or even light in a small enough wire due to the friction. The north and south magnets flow in opposite directions and twist around each other in a double helix. It also creates what is know as right hand twist and is what imparts spin.
