Document Type and Number:
WIPO Patent Application WO/2022/004428
Kind Code:
A1
Abstract:
Where a position of a second magnetic field generator changes relative to a first magnetic field generator (132) and a magnetic sensor (150), both the direction and the intensity of a second magnetic field (M4) applied from the second magnetic field generator to the magnetic sensor (150) change. A relative angle (δ) formed by the direction of a first magnetic field (M3) and the direction of the second magnetic field (M4) applied to the magnetic sensor (150) is larger than 0° and smaller than 90°.
