ABSTRACT:
A test circuit having a drive winding with parallel conducting segments and a plurality of sense elements used for the nondestructive measurement of materials. The drive winding segments have extended portions and are driven by a time varying electric current to impose a magnetic field in the test material. Sense elements are distributed in a direction parallel to the extended portions of these drive segments, with separate connections provided to each sense element. A second plurality of sense elements may also be distributed parallel to the extended portions of the drive windings, being either aligned or offset from a first plurality of sense elements.
