ABSTRACT:
There is provided a magnetic device having first and second portions with different magnetic coercivities. A magnetic field is induced in both the first and second portion. When exposed to a sufficiently high external magnetic field, the polarity of the first portion reverses generating a voltage pulse which may be detected by an external sensor. Either the first or second portion, or both, is formed from a copper alloy containing dispersed magnetic phase.
