Magnaflux is like an MRI for ferromagnetic materials
Magnuflux: Do you want to understand how Magnaflux works but are having a hard time doing it? Sometimes people learn faster if they make correlations between things they know and things they want to learn about. It works the same with Magnaflux, and you can compare it with an MRI (or Magnetic Resonance Imaging).
Let’s see how Magnaflux testing is similar to the human MRI:
It is NDT (or a non destructive test)
The procedure allows experts to “see” inside a material without having to cut into it. Taking into consideration that the human brain cannot be tested if cut open, the MRI proves incredibly useful for doctors. This is the same for the MPI (or magnetic particle inspection): pieces of material which cannot be cut can be tested for cracks or irregularities without any physical intervention.
It is performed using magnetic fields
Both the MRI and the MPI are performed making use of magnetic fields. The main difference between the two is that the MRI provides the doctors with images of the human brain, while engineers must settle with the movement of the iron oxide on the surface of the ferromagnetic material. But the procedure fulfills its purpose, so there isn’t really a need for any images…
It allows a deeper understanding of what’s inside an object
The human eye cannot see beyond the visible – this is, we do not have the possibility of “reading” the human brain or a piece of material without extra help. Both the MRI and the MPI allow us to “see” what is going on in areas that we cannot inspect directly. Using these machineries, we can better understand the inside of things… and the human body.
Remember: Magnaflux can only be used on pieces of material which can be magnetized. Most metal parts are tested in the factory; however, some can escape these tests. This is why some people ask for extra Magnaflux testing before they use the materials they have bought.
