Magnetic probe and manufacturing method thereof

The invention provides a magnetic probe which comprises a probe head which comprises a framework, three varnished wires, a copper tube and a quartz tube, the three varnished wires are wound on the framework in the X-axis direction, the Y-axis direction and the Z-axis direction respectively and are led out in a twisted-pair mode, and three twisted-pair wires are formed; the copper pipe is sleeved outside the three twisted pairs, and one end of the copper pipe is abutted against the framework; the quartz tube sleeves the copper tube, one end of the quartz tube is open, the other end of the quartz tube is sealed, and the framework is located inside the sealed end of the quartz tube which is fixedly connected with the copper tube; one end of the shielding signal line is connected with the three twisted pairs, and the other end of the shielding signal line is provided with a signal output end; and the anti-interference part coats the outer side of the joint of the probe head and the shielding signal line.
