摘要：

The limiting detection depth of subsurface defects is considered as an important efficiency factor of Magnetic Flux Leakage (MFL) method of railway nondestructive testing. This issue is particularly topical since magnetizing systems of new type with increased interpole distance are implementing. The speculative limit of detection depth is investigated by numerical simulation. Test data of NDT facilities equipped with new magnetizing system are presented.
