Differential eddy-current probes are attractive because of their insensitivity to lift-off effects. By using two similar coils wound in opposition we have a sensor that detects variations in the magnetic field along a line joining their centers. The impedance plane response of a differential probe to a flaw is rather more complicated than the signal from a single winding probe, but this is a price one must be prepared to pay for nullifying the lift-off signal
