Document Type and Number:
WIPO Patent Application WO/2021/230182
Kind Code:
A1
Abstract:
In the present invention, a magnetic probe (10) comprises: a support shaft (15); a magnetic field generator (11) that is fixed to one end of the support shaft (15) and interacts with the magnetic field and geomagnetism formed by a magnetic marker (5); and a compensation magnetic field generator (12) that is fixed to the other end of the support shaft (15) and interacts with the geomagnetism. The magnetic field generator (11) and the compensation magnetic field generator (12) are configured to interact with the geomagnetism to cancel the torque around the turning center (TC) of the magnetic probe (10).
