Magnet component is iron, cobalt, nickel and other internal structure of the atom is special, the atom itself has a magnetic moment. Under normal circumstances, the arrangement of the mineral molecules more confusion. Their magnetic region influence each other and display magnetic, waste processor tile but an outside force (such as magnetic field) under the guidance of their molecular orientation will converge, magnetic is explicitly displayed, that we are commonly known as magnets. Magnets-permanent magnets and soft iron, permanent magnets are coupled with strong magnet, makes electronic angular momentum and spin of the magnetic material into a fixed direction, soft magnetic is a power (which is also a plus magnetic methods) removed, current will slowly lose their magnetic soft iron. First and use the magnets should be Chinese, "compass" is one of the four great inventions of China.
