Abstract (en)

[origin: WO2006081796A1] The invention relates to a device and a method for the nondestructive testing of electrical conductors (1). The inventive method and device enable the magnetic field of the homogeneous conductor (1) to be fully or partially compensated (4) and thus the deviation of the magnetic field to be detected to be much more striking. The total amplitude is caused, to a larger extent, by the material defects (2) to be detected.
