basic E and M from purcells: A change in magnetic field with respect to time, will induce a current in a conducting loop that is located in that changing magnetic field. Does that mean, that if I take a power cord that is plugged into a device while it is running, so that way it is taking a load, and wrap it into loops, that I now have a current loop alternating at 60 Hz, and therefore a varying magnetic field. With this magnetic field, could I stick in another wire loop inside and power a load? IE Lets say you wrapped the cord for your toaster oven around a metal jacket hanger. Would you be able to pull a current off of this hanger?
