Hey, currently I am a high school graduate going into college in the fall, but that isn't why I am here. There has been this question eating at the back of my head. Is there some way to induce an electromagnetic field, that could then induce a current in a wire or other some such medium, to power back into the field with enough left over to power of appliances? I understand that the question borders on perpetual motion machines, as well that may be what I am asking for. It is just that with my limited knowledge of physics I have some hope that there is a way to do this. If not, be so kind as to let me know and explain to me why. If there is, post a link to where I or others may find more information on this. Thank you for your time.
