1. An assembly for a turbine engine, comprising:
a rotating assembly configured to rotate about an axis, the rotating assembly including an engine shaft and a phonic wheel threaded onto the engine shaft, the phonic wheel comprising a lubricant scoop; and
a sensor configured to measure fluctuations in a magnetic field induced by the phonic wheel during rotation of the rotating assembly about the axis;
wherein the lubricant scoop comprises a gutter projecting radially in an outward direction into the phonic wheel, the gutter projects axially into the phonic wheel, and the gutter extends circumferentially about the axis within the phonic wheel; and
wherein the engine shaft comprises a plurality of passages arranged circumferentially about the axis, and each of the plurality of passages extends axially into the engine shaft from the gutter.
