We present a new variant of an old technique which relies on the continuous tracking of a flow -advected transient eddy current that is induced by a pulsed.
They normally travel parallel to the coil's winding and flow is limited to the area of the inducing magnetic field. Eddy currents concentrate near the surface....

Since depth of penetration depends on the excitation frequency, information from a range of depths can be obtained all at once. The total amount of energy dissipated within a given period of time is considerably less for pulsed waves than for continuous waves of the same intensity, thus allowing higher input voltages to be applied to the exciting coil for PEC than conventional ECT.

DOE Scientific and Technical Information Program STIP. Pulsed eddy current PEC testing uses a step function voltage to excite the probe. When the coil approaches a conductive material, currents opposed to the ones in the coil are induced in the material — eddy currents.
