The size of most dry powder magnetic particles used in general flaw detection is
-
Less than 2 microns in any dimensiomn
-
About 3000 to 4000 microns
-
A mixture of shapes and sizes
-
Not a consideration in the test method
That's Correct!
It's Wrong!
The correct answer is a mixture of shapes and sizes. In general flaw detection, dry powder magnetic particles are used. These particles are typically a mixture of various shapes and sizes. This mixture allows for better coverage and detection of flaws in the material being tested. By having different sizes and shapes, the particles can adhere to different types of defects and provide a more accurate indication of any flaws present.
