but I don't like the idea of having to sleep right next to so much EMF radiation.\nUmmm, EMF = electromotive force. This is just the proper term for "voltage" in a circuit. It is the "E" in Ohm's Law ("E = IR" or voltage = current x resistance). This voltage is what is running through wires. While it is also used in inductors and transformers as electromagnetic induction, these components are generally shielded to prevent spurious signals or magnetic radiation from "entering" the circuit from the outside and from radiating out too as that would indicate an inefficient loss of power. Not to mention the FCC and other regulatory agencies frown on unwanted EMI\/RFI emanations. \n\nEMF - Electromagnetic Field. I probably would have been more accurate to say EMR - Electromagnetic Radiation. My mother in law believes it may contribute to my heart rhythm issues; the cardiologists haven't found anything structurally to explain the issues.\n\n\nGot a microwave or cell tower out your windows? Or a nearby airport's RADAR antenna nearby?\n\nThere's an airport 2-3 miles from us.
