What is Phase Shift and Target Identification in Metal Detectors
This is called phase shift in electrical jargon. It means the current waveform lags behind the voltage waveform. See Figure 2. Figure 2. The eddy current in the coin pushes back on the field from the detector coil, causing a phase shift, where the current and voltage wave-forms become out of step.
