Abstract: A method of inspecting a ferromagnetic object includes positioning a plurality of magnetic field sensors proximate the ferromagnetic object and when a plurality of magnetic field sensors sense respective magnetic field values at respective different locations proximate at least one surface of the ferromagnetic object, causing the plurality of magnetic field sensors to generally traverse around the ferromagnetic object.

Abstract: Methods for manipulating, positioning, and removing a lock ring for a wheel are disclosed. Manipulating the lock ring for the wheel involves increasing a separation distance between a first fastener fastened to a first end of the lock ring and a second fastener fastened to a second end of the lock ring opposite the first end. Positioning the lock ring in a lock ring groove of the wheel involves causing a lock ring positioner to position the lock ring proximate the wheel before positioning the lock ring in the lock ring groove of the wheel. Removing the lock ring from the wheel involves receiving the lock ring in at least one catcher receptacle of a lock ring positioner after removing the lock ring from the wheel.
