Abstract: The numerical simulation and theoretical analysis for Phase velocity properties of the remote field eddy current(RFEO) is presented in the paper by the electromagnetic (EM) field theory and EM computation. Comparisons of the phase velocities between the EM field and the EM wave are given. It can be seen that the research of RFEC in thin paper is of importance for Promoting the application of the RFEO technique to practical use.

Key words: electromagnetic field, phase velocity, finite element method, remote field eddy current
