Description

technical field [0001] The invention relates to the field of geological exploration, in particular to a method for manufacturing a magnetic probe of a fluxgate sensor. Background technique [0002] Fluxgate sensor, as a weak magnetic measuring device, cannot be replaced by other magnetic sensors due to its unique advantages. The core part of the fluxgate sensor is the magnetic probe, and the design of the magnetic probe often directly affects whether the sensor meets the standard. The traditional magnetic probe design is usually to wind the induction coil and excitation coil on the magnetic core first, and then process and synthesize it by opening the mold. First, the magnetic core material is generally very soft, and often requires manual winding. Since there is no suitable high hardness and thin non-magnetic skeleton to fix in advance, the difficulty of winding is further increased. Secondly, this processing method is often costly, and different shapes of magnetic probes...
