Magnet Discovery
Gauss Industrial Co.,Ltd | Updated: Dec 14, 2017

Magnet is not human invention, is a natural magnetite. Ancient Greeks and Chinese found in nature a kind of natural magnetized stone, called "magnetite." This stone can magically suck up a small piece of iron, and always swing in the same direction. Early voyagers identified the direction of the magnet as the earliest compass at sea. The earliest discovery and use of magnets should be Chinese, or "compass", and one of the four inventions in China.


After thousands of years of development, today's magnet has become a powerful material in our life. Through the synthesis of different materials alloy can reach the same effect with the magnetite, but also can improve the magnetic force. Artificial magnets appeared in the 18th century, but the process of making stronger magnetic materials was slow until the Alnico was made in the 1920s. Ferrite was subsequently made in the 1950s, and rare earth magnets were made in the 1970s [Rare Earth magnets including NdFeB and SmCo]. At this point, magnetic technology has been rapid development, the magnetic material also makes the components more miniaturized.
