The Magnetic Sensor is a sensor capable of measuring the magnitude and direction of a magnetic field. The sensor usually refers to a sensor that converts the magnitude and variations of a magnetic field into electric signals. The sensor includes a sensing chip having a magneto resistive element for sensing a magnetic vector and a magnet for biasing the magnetic vector sensed by the magneto resistive element. The sensors are used to detect magnetic fields and they are essential tool for many engineering applications. The Magnetic Sensor is made for use in the various commercial and industrial applications.
