There is disclosed a method and apparatus for identifying an electrical device. The method comprises the steps of 1) providing an identification code to a controller, 2) operatively connecting the controller to an electrical load, 3) using the controller to create a sequence of timed electromagnetic field pulses in accordance with the identification code, 4) detecting said sequence of timed pulses by means of a passive probe, and 5) translating the sequence of timed pulses into the identification code to identify the device. The sequence of timed electromagnetic field pulses comprises an initial pulse followed by one or more pulse groups. Each pulse group consists of a time delay followed by at least one subsequent pulse. The apparatus comprises a circuit with at least an electrical load, an electromagnetic field generator, a current varying means, and a power source operatively connected together in series. The apparatus also comprises an identification code for identifying the device and a controller for controlling the current varying means in accordance with the identification code. The controller controls the current varying means to cause the electromagnetic field generator to emit a sequence of timed electromagnetic field pulses sized and shaped to be detected by a passive probe.
