A magnetic sensor, also called a magnetometer, is a physical electronic component used for 3D tracking devices such as head-mounted displays and controllers. It works by measuring the strength and direction of a magnetic field. Magnetometers in consumer electronics measure a magnetic field along 3 perpendicular axises of X, Y, and Z.
Magnetometers measure magnetic flux density.
In virtual reality and augmented reality, magnetometers are part of IMUs or alongside them inside a device.
Magnetometers can be used with permanent magnets to make a permanent magnet 3D tracking system.
