Abstract
A novel test method enables physical properties in ferromagnetic metals to be more reliably measured with induced eddy current flow. An adverse Barkhausen effect is prevented during the test measurements to enable detection of extremely small conductivity changes in the particular ferromagnetic metal object being tested.
