Magnetic Particle Inspection (MPI)
Detect surface and near-surface defects in ferromagnetic materials. Reliable inspections support safety, quality and asset integrity.
What is Magnetic Testing?
Finding surface defects in ferromagnetic materials
Magnetic Testing (MT), also known as Magnetic Particle Inspection (MPI), is an NDT method for checking the surface integrity of ferromagnetic materials. By magnetising the material and applying magnetic particles, surface and near-surface indications become clearly visible, enabling rapid evaluation of material integrity, weld quality and material condition.
Benefits
- Detection of surface and near-surface defects in ferromagnetic materials
- Fast and cost-effective inspections with immediate indication visibility
- Suitable for workshop and on-site applications across a wide range of industries

Performance overview
Strengths and limitations of Magnetic Testing
Strenghts
- Rapid inspection of large surfaces
- Relatively low equipment cost
- Detection of surface and subsurface defects
- Immediate interpretation of indications
- Can be used in workshop and on site
- Surface preparation is less critical than with Penetrant Testing (PT)
Limitations
- Restricted to ferromagnetic materials
- Requires supply of electricity
- It is sometimes unclear whether the magnetic field is sufficiently strong to give good indications
- Cannot be used if thick paint coating is present
- Some of the paints and particle suspension fluids can cause fire risk, particularly in a confined spaces
