| description | The invention discloses a fluxgate sensing chip with low power consumption, low noise and high sensitivity. A magnetic core of the fluxgate sensing chip is a multi-section porous magnetic core; the multi-section porous magnetic core is of a rectangular plate structure and is formed by at least two sections of porous magnetic cores side by side along the short sides of a rectangle. Wherein the single-section porous magnetic core is a rectangular plate of which the middle is provided with through holes; long-strip-shaped spaced through holes are formed between every two adjacent porous magnetic cores in the long edge direction of the two porous magnetic cores. The exciting coil and the induction coil of the solenoid structure are sleeved on the outer surface of the multi-section porous magnetic core in an insulating manner; the excitation coil and the induction coil are independently arranged at a preset interval or the single-turn coils of the excitation coil and the induction coil are alternately arranged on |
