MAG PARTICLE EXAM LEVEL 2 QUESTIONS AND VERIFIED
CORRECT ANSWERS 100% GUARANTEED PASS

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
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
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
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
a) longitudinal
What type of magnetization uses the formula: Ampere-turns= 45,000/L/D?
a) circular
b) longitudinal
c) parallel
d) vectored
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
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
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
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
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
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
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
c) It is easier to use for field inspection with portable equipment
