<p>In order to precisely measure a magnetic field angle or a rotation angle, even when a magnetic flux generating body is rotating at high speed, with a configuration in which a non-magnetic conductor (electrical conductor) is placed near the magnetic flux generating body or a magnetic sensor, this magnetic field angle measurement device, which is provided with a magnetic sensor (70) sensitive to magnetic field direction, a non-magnetic first conductor (240), and a non-magnetic second conductor (242), is configured such that: the magnetic sensor is placed between the first conductor and the second conductor; and a magnetic field induced in the magnetic sensor by eddy current in the first conductor, and a magnetic field induced in the magnetic sensor by eddy current in the second conductor cancel each other out.</p> |
