Metal Detectors And Boom Barriers

As we are considered amongst well known organizations, we are engaged in trading, distributing and supplying and exporting a large range of Metal Detectors and Boom Barriers in Indore, Madhya Pradesh, India. The simpleest from of a metal detector consists of an alternating current that passes through a coli producing an alternating magnetic field. if a piece of electrically conductive metal is close to the coil, eddy currents will be induced in the metal and this produces a magnetic field of its own.if another coil is used to measure the magnetic field (acting as a magnetometer),the change in the magnetic field due to the metallic object can be detected.
