PROBLEM TO BE SOLVED: To provide a magnetic sensor having a Hall element with a spinning current circuit for reducing magnetic offset, which offers a reduced magnetic offset.SOLUTION: A magnetic sensor device includes a current path changeover switch that is connected to each terminal of a Hall element to switch between a first current path and a second current path, an output path changeover switch that is connected to each terminal of the Hall element to switch an output path for a Hall voltage between a first output path and a second output path, and a subtractor that outputs a difference between an output voltage from the first output path and an output voltage from the second output path, where the first output path and the second output path have the same wiring resistance.SELECTED DRAWING: Figure 1 |
