Abstract
A detector for magnetizable materials operates remotely to determine a amplitude and phase modification of an exciting magnetic field caused by the magnetizable materials. These amplitude and phase measurements are used to create a phase-amplitude trajectory in phase amplitude space, which may be finely divided to distinguish among a number of different types of components.
