Magnetic sensor, also known as a magnetic field sensor is classified in terms of measuring a complete magnetic field or vector-components of the magnetic field. Permanent magnets such as neodymium magnets are used to trigger the magnetic sensors in several applications. Magnetic sensor is used to identify magnitude and direction of magnetic field. It comprised of rotating sensor tip which measures both transverse and longitudinal magnetic fields around the objects. Magnetic sensor uses “Hall Effect” (produces voltage difference across electrical conductor, transverse to electric current) transducer that measures vector component of magnetic field near the sensor tip. Magnetic Sensor also enables to detect and read data from microelectromechanical systems, such as temporary memory processing unit, hard drives, MRAMs. Advancement of small scale ‘Micro Electro Mechanical Systems’ (MEMS) for detecting and measuring magnetic fields is primarily driving the market along with growth of consum...
