>The interesting concept here is that he's using a property known as Lenz's Law that creates something called back EMF through those coils of wire that used to have energy running through them. Lenz's law simply states that, like Newton's law of an "equal and opposite reaction," there's an opposing force counter-acting the force in play. It's like the opposite reaction of an astronaut falling towards a planet: inertia. Neither force is created, nor destroyed. All energy is conserved. Idiot troll.
