used throughout the Air Corps.
c. The materials that may be inspected by this method must be
capable of being magnetized. Alloys of steel that are only faintly
magnetic do not, as a rule, produce satisfactory results.

46. Magnaflux testing equipment.-The equipment necessary
for conducting an inspection consists of the following major parts:
a. Magnetizing apparatus.--This unit (fig. 9) provides the means for
magnetizing the parts to be inspected, and may be operated by either
direct or alternating current. The alternating current system is not,
at present, being used in the Air Corps and will therefore not be
described.
(1) The direct current magnetizer is supplied with current from
storage batteries contained in the unit, and maintained in a charged
condition by means of an integral battery charger. The magnetizing
current is controlled by means of switches and a rheostat shown at the
left of the illustration.TM 1-423
