 Magnet (magnet) can be generated magnetic field, for a magnetic dipole, to attract the magnetic material such as iron, nickel, cobalt and other metals. The determination is based on thin poles hanging a magnet, pointing to the north pole or N pole is called the Arctic means, point to the south pole as a guide pole or S pole. (If you want to become a great magnet the earth, the earth's magnetic north pole is currently the S pole, magnetic South Pole is the N pole.) Magnets of different poles is attraction, with the most is exclusive. Guide and refer to the Arctic polar attraction, guide pole and the guide pole repulsion, refers to the North Pole and the Arctic means repulsion. 
 The main component 
 Magnet, also known as a magnet, is the presence in the surrounding magnetic field and their own internal objects or material, is divided into two major categories of natural and man-made. Artificial magnets are usually made of metal alloy, with a strong magnetic. Can be divided into "permanent magnet" and "permanent magnet", or "hard-magnetic" and "soft." Natural magnet main components: iron oxide, chemical formula Fe3O4, often referred to as "magnetic iron oxide." Magnetic black crystals. Can be seen as consisting of ferrous oxide and iron oxide compounds. Due to the iron oxide crystals in the presence of two different valence states of ions, one third of Fe2 +, two-thirds of Fe3 +, is a complex compound. It does not dissolve in water, can not react with water. Reaction with acid, insoluble in alkali. The main system for primer and paint, magnetic materials for the electronics industry, is also used in the construction industry, anti-rust agent.
