In this paper, the magneto-eddy currents on SPR have been numerically simulated and experimentally investigated for non-destructive testing of the SPR. The magnetic field- and electromagnetic field-driven magnetic force distribution was characterized with respect to the measurement target formation. First, finite element analysis (FEA) was performed to characterize the magneto-eddy current effects by focusing on the correlation between permanent magnet-induced attraction force and eddy current. Second, based on the FEA, a magneto-eddy current sensor (MECS) to measure the magneto-eddy current effects on SPR was designed and instrumented. The MECS combining the magnetic force sensor and the eddy current sensor non-destructively enables measuring the magneto-eddy current of SPR configuration like a combination of carbon fiber reinforced plastic (CFRP) and aluminum (Al). Finally, the 3-axis scanning experiments were performed to validate performing MECS by combining the magnetic testing for the steel rivet and the eddy current testing for the Al plate. As a result, the magneto-eddy current effects can be used to defect the defects of SPR available for non-destructive SPR quality assessments.
