Actual Questions and CORRECT
ANSWERS
The interpretation of magnetic particle indications may be aided by:
a) observing with a magnifying glass
b) observing the indications as they are formed
c) reproducing the indication residually
d) all of the above - CORRECT ANSWER✔✔- d) all of the above
Residual magnetism may be beneficial as an aid:
a) in the deposition of weld metal
b) in interpretation and evaluation of indications
c) in demagnetization
d) all of the above - CORRECT ANSWER✔✔- b) in interpretation and evaluation of
indications
An interruption in the normal physical structure or configuration of a part which produces an
MT indication is called:
a) a discontinuity
b) a defect
c) an indication
d) a deformation - CORRECT ANSWER✔✔- a) a discontinuity
Comparing parts that have been circularly magnetized and those which have been
longitudinally magnetized, which retains the most objectionable residual field if not
demagnetized?
a) longitudinal
b) circular
c) vectored
d) remnant - CORRECT ANSWER✔✔- a) longitudinal
,What type of magnetization uses the formula: Ampere-turns= 45,000/L/D?
a) circular
b) longitudinal
c) parallel
d) vectored - CORRECT ANSWER✔✔- b) longitudinal
Why are large soft contact areas such as lead or copper braid used for surfaces or headstocks?
a) to increase the contact area and reduce the possibility of burning the part
b) because of their low melting points
c) because the help heat metal, thus facilitating magnetic induction
d) to increase the contact area and flux density - CORRECT ANSWER✔✔- a) to increase the
contact area and reduce the possibility of burning the part
A rough forging that has received no further processing is magnetic particle tested. An
indication is observed to run in every direction. It appears to extend deeply into the part and
perpendicular to the surface. It is very sharp. What is the probable identity of the indication?
a) forging burst
b) lap
c) flake
d) seam - CORRECT ANSWER✔✔- a) forging burst
A gear with case-hardened ground teeth and hub ends is MT tested. Individual indications are
detected on five of the teeth and on the one end surface of the hub. Although the indications
are very sharp and distinct, they do not break over the edges of the part. What is the probable
identity of the indication?
a) grinding cracks
b) inclusions
c) porosity
d) quench cracks - CORRECT ANSWER✔✔- a) grinding cracks
, If an overall pattern (sometimes circular lines) appears on the test surfaces, how should the
inspector reprocess the test
piece?
a) retest at a higher amperage
b) demagnetize
c) retest at a lower amperage
d) both a and b - CORRECT ANSWER✔✔- c) retest at a lower amperage
A prime consideration when selecting a powder to be used as a magnetic particle medium is
to select a powder that:
a) provides a high contrast to the surface being tested
b) provides a low contrast to the surface being tested
c) will adhere to the surface being tested
d) requires a high demagnetization current to remove it - CORRECT ANSWER✔✔- a)
provides a high contrast to the surface being tested
When testing for fine shallow surface cracks, the preferred MT method should be:
a) dry AC
b) dry DC
c) wet AC
d) wet DC - CORRECT ANSWER✔✔- c) wet AC
Which of the following is an advantage of the dry method over the wet method?
a) It is more sensitive to fine surface cracks
b) It is more capable of providing full surface coverage on irregularly shaped objects
c) It is easier to use for field inspection with portable equipment
d) It is faster than the wet method when testing a number of small parts - CORRECT
ANSWER✔✔- c) It is easier to use for field inspection with portable equipment
When testing a bar with an L/D ratio of four in a ten-turn coil, the required current would be:
a) 45,000 amperes
