Burst eddy current testing with diamond magnetometry [PDF]
Applied Physics Letters, 2022 In this work, a burst eddy current testing technique based on the employment of a diamond nitrogen vacancy (NV) center magnetometer with the Hahn echo (HE) sequence is demonstrated. With the confocal experiment apparatus, the HE-based NV magnetometer attains a magnetic sensitivity of 4.3 nT/Hz and a volume-normalized sensitivity of 3.6 pT/Hz mm−3 ...

Characteristics of Eddy Current Attenuation and Thickness Measurement of Metallic Plate
Chinese Journal of Mechanical Engineering, 2019 In eddy current testing, the law of attenuation of eddy current (EC) is of great concern. In conductive half space under the excitation of uniform magnetic field, the EC density decreases exponentially in the depth direction.

Depth of penetration effects in eddy current testing [PDF]
, 2012 The simple depth of penetration equation used for most eddy current calculations does not take into account the effect of the size of the coil or the effect of flaw morphology. The work described in this paper describes use of the CIVA eddy current model
