Magnetic detector |
摘要 |
A magnetic detector includes a moving body which is multipole-magnetized and which is rotated synchronously with a rotational axis; a magnetic resistance element for detecting a change in magnetic field of the rotating moving body; a processing circuit portion for outputting a signal corresponding to the multipole magnetization of the moving body in accordance with the change in resistance value of the magnetic resistance element due to the change in magnetic field; and a magnet for applying a bias magnetic field to the magnetic resistance element.
