Magnetic particle examination (MT) is a very popular, low-cost method to perform nondestructive testing of ferromagnetic material. MT is an NDT method that checks for surface discontinuities but can also reveal discontinuities slightly below the surface.


Navitus NDT use magnetic particle testing to locate surface and sub-surface discontinuities in ferromagnetic materials such as weldments, crane hooks, turbine blades, machine parts, gears, vessels, and piping.
