The typical MPI machine is a big, heavy, high current Full Wave DC Machine, which is expensive to purchase, operate and maintain.
You are probably looking for surface cracks, because the surface is where stresses are concentrated and materials crack. AC magnetization concentrates the magnetic field on the surface (skin effect) which is also contour following for the best sensitivity to surface cracks. The polarity (+/-) shifting increases particle mobility. AC Magnetic Particle machines are less expensive to own and operate. AC is also a natural at demagnetizing.

For example, the image on the left shows the following options:
These features come standard:
Multi-Directional (rotating field) uses a dual output power supply that powers the Coil and Heads from 2 legs of a 3-Phase system, creating a rotating or swinging field that detects cracks and other surface flaws in any orientation in less than the normal inspection time.
Coil - Head Shot Switch (for use with Single Power Supply): Quick and easy switching - when the part is clamped using the clamping lever, current flows through the part. When unclamped, current is directed to the coil.
Frames:
PTS MAS Bench units can be powered with:
Conventional AC or AC/HWDC portable power supply.
Plug one side into the ground socket and the other cable to Head Shot or Coil socket. Or, use with the optional Coil - Head Shot Switch. When this Switch is employed and the part is clamped using the clamping lever, current flows to the part. When unclamped, current is directed to the coil.
More information about this power supply can be found here:
Duo Power Supply – Two Power supplies in one.
Multi-Directional magnetization using two out of phase circuits creates a rotating or swinging field that detects cracks in any orientation in the same test sequence.
