What are the effects of Magnetic Field Sensor in Android ?

- The Magnetic Field Sensor measures the ambient magnetic field in the x,y,z axis.

- This Coordinate System is aligned just like the accelerometers sensors.

- The Unit of Magnetic Field Sensor are microteslas(uT).

- This Sensor can detect the Earth's Magnetic Field and therefore tell us where north is.

- This Sensor is also referred to as the compass,and in fact the <uses-feature> tag uses
android.hardware.sensor.compass as the name of this Sensor.

- Because the sensor is so tiny and sensitive,it can be affected by magnetic fields generated
by things near the device,and even to some extent to components within the device.

- Therefore the accuracy of the magnetic field sensor may at times be suspect.
