Magnets History

by Administrator | post a comment

The ancient Greeks and Chinese people find nature a kind of natural magnetization of stone, called "magnet." This stone can magically pick up small pieces of iron sheets, and free to swing always point in the same direction. Early sailors call this magnet as the first to identify the direction of the compass at sea. After thousands of years of development, today has become a magnet strong material in our lives. By alloy synthesis of different materials to achieve the same effect with a magnet, but also can improve the magnetic force. In the 18th century there have been man-made magnets, but the manufacturing process of a stronger magnetic material is very slowly until the 1920s to produce aluminum-nickel-cobalt (Alnico). Subsequently, the 1950s produced the ferrite (Ferrite), 70 years to produce rare earth magnets. Rare Earth magnet including neodymium iron boron (NdFeB) and samarium cobalt (SmCo)]. Thus, magnetic Technology has been developing rapidly, so that the element of magnetic materials are also more compact.
