Summary:The invention relates to a method for processing a nanocrystalline soft magnetic sensor, which comprises the following steps of: heating ingredients comprising 83.5- 85.5 wt% of Fe, 7-9 wt% of Si, 1.4-2.1 wt% of B, 1.2-1.5 wt% of Cu, 0.1-0.7 wt% of P, 2.5-4 wt% of Nb and 1-2 wt% of V in a high-temperature furnace, smelting, spraying the smelted alloy onto a high-speed rotating copper roller to prepare an iron-based nanocrystalline strip of an amorphous alloy, putting the iron-based nanocrystalline strip into the high-temperature furnace, crystallizing and forming, winding a coil, connecting a lead wire with a basic electric appliance, wherein high initial magnetic conductance is met and exciting current is reduced by using the magnetism of the iron-based nanocrystalline, the working flux density is very strong, the interference of an external stray magnetic field is reduced, and meanwhile, the magnetic gain coefficient of the sensor is increased, so that the output sensitivity of the sensor is greatly improve
