<p>PROBLEM TO BE SOLVED: To accurately detect a cable to be probed by detecting the magnetic flux generated from a pilot signal by means of a galvanomagnetic element group having a specific constitution. SOLUTION: In a magnetic sensor 400, each detection coil PX1, PX2, PY1, and PY2 is divided into three split coils 405 adjoining to each other in the peripheral direction and the coils 405 are connected in series. The coils PX1, PX2, PY1, and PY2 each composed of the three split coils 405 are housed in an external case. When the magnetic sensor 400 is constituted by using the coils PX1, PX2, PY1, an PY2 each composed of the split coils 405 adjoining to each other in the peripheral direction, the sensor 400 becomes effective, because the magnetic sensor 400 shows uniform sensitivity regardless of the position of a quad and can more accurately detect a cable to be probed.</p> |
