Abstract
A magnetic sensor includes a magneto-resistive element configured to output a signal and a detection circuit configured to receive the signal. The detection circuit includes a regulator configured to supply a potential to the magneto-resistive element, a first current path configured to electrically connect the magneto-resistive element to the regulator, a second current path, a switch, and a diagnostic circuit connected to the second current path. The second current path includes, and is configured to electrically connect the magneto-resistive element to the regulator via the resistor. The switch is configured to select one of the first current path and the second current path, and electrically connect the magneto-resistive element to the regulator via the selected one of the first current path and the second current path.
