China is the earliest application of magnetic country, in the 4th century b. c. , the country made the world's first compass, become one of the four great inventions of China. Magnetism in the history of the first monograph about magnetic is Britain ( WGilbert) Gill Herbert 'on a magnet' ( 1600) , this book introduces the knowledge about magnetic books at that time. Magnetic as a science, however, through the first half of the 19th century began to develop.   In 1820, the Danish physicist oersted found that current magnetic, opened the prelude of magnetoelectric link between;   At the end of 1820, the French physics ampere prove electricity round coil and ordinary magnet has the phenomenon of attraction and repulsion.   In 1831, British scientists Faraday discovered electromagnetic induction phenomenon, and put forward the law of electromagnetic induction, so as to reveal the inner link between electricity and magnetism.   Later, Scottish scientists maxwell, electromagnetic connections established rigorous electromagnetic field theory. He developed the Faraday thought, in the form of mathematical summed up the connection of electric field and magnetic field, the maxwell's equations.
