Question 1
Which discontinuity is most likely to produce a clear relevant indication during magnetic particle testing?
Correct Answer:
A surface-breaking crack in ferromagnetic steel that lies roughly perpendicular to the magnetic field
Question 2
Why is magnetic particle testing generally not used on aluminum parts?
Correct Answer:
Aluminum is not ferromagnetic and cannot hold the required magnetic flux for MT
Question 3
When current is passed directly through a round bar between head stocks, what field is primarily produced and which discontinuities are best detected?
Correct Answer:
A circular field that best reveals longitudinal discontinuities
Question 4
A shaft is magnetized with a coil shot. Which field and discontinuity orientation are most associated with that setup?
Correct Answer:
A longitudinal field that best reveals circumferential cracks
Question 5
Why are two magnetization directions commonly required in magnetic particle testing?
Correct Answer:
Because a single field direction may miss discontinuities that run nearly parallel to that field
