Vehicle detectors use _ of ferrite magnet ndfeb strong magnet manufacturers

Ferrite magnets of vehicle detectors use found in the nature of ancient Greek and Chinese people have a natural to be magnetized rocks as magnets, a thin plate, they can absorb magic and always points to the same direction after random oscillation, we Chinese people are just using the characteristic of the magnet invented the compass, used to tell direction on the sea, is one of the four great inventions of ancient China. Below pictures for vehicle detector magnet can not only attract contain iron material, also can attract the containing cobalt and nickel material, we can also use the properties of the magnet to produce a detector, if there are any iron material, will send out the drops dripping noise. Detectors ready, how to use? The dynamic vehicle detector are derived from the nature of the magnet. Magnets attract each other with iron on the controller, make wire connected with iron, therefore, circuit is conduction, buzzer sounded. Warm prompt: when using the detector, is to make a magnet attracts iron metal in contact with the conductor, this circuit can get through, if only the magnet to absorb iron metal, without contact with the conductor, buzzer will not emit sound, because of the ferrite magnets do not conduct electricity.
