Study on the Impact of Pole Spacing on Magnetic Flux Leakage Detection under Oversaturated Magnetization

Magnetic flux leakage (MFL) inspection employs leakage magnetic fields to effectively detect and locate pipeline defects. The spacing between magnetic poles significantly affects the leakage magnetic field strength. While most detectors typically opt for moderate pole spacing for routine detection,...
