The invention discloses a flux gate sensor magnetic probe manufacturing method. The method comprises the following steps: A, a 3D printing model of a flux gate probe and a feedback coil is built; B, anon-magnetic skeleton of the probe is printed; C, a magnetic core is placed and fixed in the cavity of the non-magnetic skeleton; D, an induction coil and an excitation coil are wound on the non-magnetic skeleton; E, the skeleton of a feedback coil is printed; F, an enameled wire is wound in a coil groove on the outer wall of the skeleton of the feedback coil, and a coil is manufactured; and G, the probe and the feedback coil are assembled to manufacture a flux gate sensor magnetic probe. According to the flux gate sensor magnetic probe manufacturing method disclosed in the invention, flexibility is achieved, the process can be adjusted, and quick processing can be carried out for different models.
