Magnet magnets known, is in the magnetic field within itself and around the object or material is divided into two major categories of natural and man-made. Artificial magnets usually made of a metal alloy, a ferromagnetic. Magnetic NdFeB magnets are arranged in size, samarium cobalt magnets, alnico magnets, ferrite magnets. All of the magnets can be simply divided into "permanent magnet" and "non permanent magnet." The permanent magnet may be natural products, permanent magnets are only in certain conditions appear magnetic. A magnet to produce a magnetic field to attract ferromagnetic material such as iron, nickel, cobalt and other metals. The midpoint of the bar magnet suspended by a thin line, still, it will be pointing to the ends of the earth north and south, called the finger pointing to the north end of the North Pole or N-pole, one end of the guide points to the south pole or S pole. Between the magnet and the magnet with pole phase exclusion, unlike poles attract each. Horsepower magnet with sophisticated equipment and reliable quality, efficient, and welcome new and old customers to inquire. Source: NdFeB magnets, magnet, magnetic factory-http :/ / www.malict.com
