1. A magnetic particle testing mechanism for testing for defects in an axle of a landing gear assembly, comprising:
a conductor mechanism, wherein the conductor mechanism is configured to:
apply a magnetic particle substance onto a portion of the axle; and
generate a magnetic field within or around the portion of the axle,
wherein generating the magnetic field causes a magnetic field distortion associated with a defect in the axle that attracts the magnetic particle substance indicating a location of the defect in the axle and wherein the conductor mechanism is a tube structure with a center void and a plurality of spray nozzles along a length of an outer casing of the tube structure.
