Magnetic flux leakage testing refers to the use of magnetic traces to display defects in ferromagnetic materials and their products.Magnetic flux leakage testing: Magnetic particle testing can detect small defects that are exposed on the surface and cannot be directly observed with the naked eye or with the help of a magnifying glass. It can also detect near surface defects that are not exposed but buried a few millimeters below the surface.

Magnetic flux leakage testing (MFL) is a non-destructive testing technique that detects defects by detecting magnetic leakage fields. When magnetizing the measured ferromagnetic material with a magnetic saturator, if the material is continuous and uniform, the magnetic induction lines in the material will be constrained within the material.

Magnetic flux leakage testing and ultrasonic testing are two different detection methods mainly used to detect defects or cracks in metal materials.

Magnetic flux leakage testing (MFL) refers to the formation of a leakage magnetic field on the surface and near surface defects of ferromagnetic materials after magnetization
