Abstract
In multiple magnetic sensors, for a correlation function between a magnetic field applied from a magnet and a value of the magnetic field detected by the magnetic sensor at a first temperature, the value detected by the magnetic sensor when the magnetic field applied from the magnet is 0 is set to be a first offset value. For a correlation function between a magnetic field applied from the magnet and a value of the magnetic field detected by the magnetic sensor at a second temperature, the value detected by the magnetic sensor when the magnetic field applied from the magnet is 0 is set to be a second offset value. The second temperature is higher than the first temperature. A values of applied magnetic fields detected by first and second magnetic sensors are opposite in polarity.
