Magnetic sensors are used to determine the direction and magnitude of a magnetic field. These sensors are used in magnetometry and compassing applications. When the magnetic sensor comes close to a specific type of magnet, it changes state to indicate the presence of the magnet or to set off specific actions.
Products that might incorporate magnetic sensors include personal GPS systems, cell phones, security systems, elevators, gates, automobiles, airplanes, and boats. Industrial technology companies also use magnetic sensors in specialized industrial equipment.

Magnetic sensors can experience interference from an electrical field, such as the field emitted by a computer. They can also become imprinted by an extremely strong magnetic field so that the signal of the large field overrides any new data.
Some types of metals affect magnetic fields and alter the signal that a magnetic sensor receives. These include nickel, steel, and iron. The properties of nearby metals should be considered when installing magnetic sensors in a device. You might be able to calibrate the device to account for nearby metals.
Some companies that make magnetic sensors include Honeywell, Carlo Gavazzi, GMW Associates, Infineon, and NVE Corporation. To learn more about magnetic sensors, check out the links to the left from Business.com.
