Magnetic particle inspection (MPI) is an NDT testing process for detecting surface and subsurface discontinuities in ferrous materials. The process inserts a magnetic field into the part that can then be magnetized through direct or indirect magnetization.

When the magnet is motionless with respect to the coil, no current is induced in the coil, as in Figure 20.33. In addition, moving the magnet in the opposite direction (compare Figure 20.33 with Figure 20.33) or reversing the poles of the magnet (compare Figure 20

3.2.1 Mechanism. Magnetic-based detection methods replace fluorescent beads and optical detectors, used in traditional devices, with magnetic beads (MBs) and magnetic sensors. In a magnetic-based detection process, MBs are dispersed in a fluid flowing inside a microchannel and detected by specialised magnetic sensors.

· With the advent of cryogenic magnetometers (Collinson, 1983), measuring the weak magnetizations of sediments and sedimentary rocks is no longer a major problem. Red sedimentary rocks – so-called red beds – possess, in addition to depositional remanence, a CRM (10 −3 –10 −1 A/m) carried principally by hematite pigment and cement.

Inspectors commonly use magnetic yokes to generate a magnetic field for magnetic particle inspections (MPIs). This approach is not only used in the field, but also in shops. In this case, a longitudinal magnetic field can be induced in a test object or in a limited area of a test object using a hand held yoke.
