Abstract
According to one embodiment, a magnetic sensor includes a first conductive portion, a second conductive portion, a sensor portion, a temperature control element, and a controller. The sensor portion includes a first magnetic member provided between the first conductive portion and the second conductive portion. A direction from the temperature control element to the sensor portion includes a component of a second direction crossing a first direction from the first conductive portion to the second conductive portion. The controller is configured to change a temperature of the temperature control element.
