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.

We claim: 1. A packaged product comprising: a plurality of constituent package components assembled to produce the packaged product wherein at least two of the package components include magnetizable filaments of at least two distinguishable species in predetermined different ratios to enable an identification of the components based, at least in part, on the predetermined ratios using at least amplitude discrimination. 2. The packaged product of claim 1 wherein the number of constituent package components assembled exceeds the number of species of magnetizable filaments incorporated into the constituent package components. 3. The packaged product of claim 1 wherein one of the constituent package components is a box. 4. The packaged product of claim 1 wherein one of the constituent package components is an instructional insert. 5. The packaged product of claim 1 wherein the two species of magnetizable filaments are incorporated into a material selected from the group consisting of: paper, solid polymer, paint, textile, and ceramic. 6. The packaged product of claim 1 wherein the two species are inserted into the constituent package components in predetermined absolute amounts. 7. The packaged product of claim 1 wherein species are selected from the group consisting of: Permalloy, Nickel Iron alloy, Supermalloy, and Fecralloy, ferritic Stainless Steel, low carbon steel, and Metglas. 8. A method of packaging a product comprising the steps of: (a) incorporating in each of at least two constituent package components magnetizable filaments of at least two distinguishable species in predetermined different ratios to allow the at least two species to be distinguished using at least amplitude discrimination; and (b) assembling the constituent package components together such that each constituent package component is differentiated from the other based on the predetermined different filament ratios. 9. The method of claim 8 wherein the number of constituent package components assembled exceeds the number of species of magnetizable filaments incorporated into the constituent package components. 10. The method of claim 8 wherein one of the constituent package components is a box. 11. The method of claim 8 wherein one of the constituent package components is an instructional insert. 12. The method of claim 8 wherein the two species of magnetizable filaments are incorporated into a material selected from the group consisting of: paper, solid polymer, paint, textile, and ceramic. 13. The method of claim 8 wherein the two species are incorporated into the constituent package components in predetermined absolute amounts. 14. The method of claim 8 wherein species are selected from the group consisting of: Permalloy, Nickel Iron alloy, Supermalloy, and Fecralloy, ferritic Stainless Steel, low carbon steel, and Metglas.
