Why are magnetic particles available in different colors?
-
For color contrast with the part surface.
-
To enhance the detection of indications
-
For both A and B
-
Different colors are used with different magnetic flux values.
That's Correct!
It's Wrong!
Magnetic particles are available in different colors for both A and B. The first reason is for color contrast with the part surface, which makes it easier to see the magnetic particles and any indications or defects on the surface. The second reason is to enhance the detection of indications, as different colors can provide better visibility and contrast depending on the type of part being inspected. Therefore, both reasons contribute to the availability of magnetic particles in different colors.
