A finite element study of the remote field eddy current phenomenon

Inspection of Metallic Plates Using a Novel Remote Field Eddy Current NDT Probe

“…The first results of Finite Element Modeling (FEM) of the RFEC phenomena [3]- [4] revealed some unique field patterns in RFEC fields: the "potential valley" (Fig. 3) and the "phase knot" (Fig.…”

“…They appeared to be resulted from the two oppositely moving signal paths. Further FEM studies [4]- [5] explained the phenomena using Poynting vector patterns in the RFEC field (Fig. 5).…”

Three Dimensional Simulation of Remote Field Eddy Current Nondestructive Testing Phenomena

“…phase angle FE modeling studies [3], [4] have served to explained the phenomena using the field and Poynting vector patterns in the RFEC field (Fig. 3).…”

“…However, the underlying physics of the RFEC phenomena was not well understood until mid 80's. The Finite Element (FE) modeling of RFEC revealed some fundamental electromagnetic field characteristics around an RFEC probe inspecting a pipe [3], [4]. Fig.…”

3-D Finite Element Modeling of the Remote Field Eddy Current Effect

“…A typical RFEC probe [4,5] with exciter to sensor spacing of three pipe diameters is shown in Fig. 1 b for the case of transmission gas-pipeline.…”
