The paper begins with a brief summary of previous work done by the authors on gaining a better understanding of the remote field eddy current (RFEC) phenomenon and expanding the range of applications. It then introduces three new findings: (1) Modeling and experimental study of the RFEC phenomenon as observed from one side of both ferromagnetic and non-ferromagnetic plates. (2) Numerical prediction of possible existence of the RFEC phenomenon external to conducting tubes. (3) Numerical study of its possible application in underwater target detection problems.
