http://www.futureelectronics.com/en/Pages/index.aspx - This video explains what is a Magnetometer and tell you about Future Electronic’s line-up of Magnetometer products. A magnetometer is a device that can measure magnetic field strength or direction. Combined with other sensing devices and microprocessors, electronic compasses, remote control or location-based service can be achieved. MEMS magnetometers can acquire accurate orientation-independent compass heading information when used in conjunction with a three axis accelerometer.
