| Abstract: | Among dozens of non-destructive testing methods,the electromagnetic non-destructive detection method is developed on basis of electromagnetic theory,and it can conduct defect detection and performance evaluation on materials and components because of their changes of electromagnetic properties.Comparison from principle,system construction and application are given among the three traditional electromagnetic detection method including eddy current testing,and the other two new electromagnetic detection methods(alternating current field measurement and electromagnetic tomography).Some conclusions are drawn to provide references for the comprehensive application and development of these electromagnetic non-destructive detection methods. |
