摘要：

The comparison of residual Magnetic Flux Leakage (MFL) with traditional MFL method was carried out as applied to rail nondestructive testing. The mechanisms for the residual magnetization of rails are considered. It is concluded that the traditional Magnetic Flux Leakage method is more effective as compared with one based on D degrees rail remanence.
