Application of Magnets on Maglev Train
Maglev train is a maglev high-speed train system with a non-contact electromagnetic levitation, guidance and drive system. Its speed of up to 500 kilometers per hour, is the world's fastest ground passenger transport, a fast, climbing ability, low energy consumption, low noise, safe and comfortable, non-fuel oil, less pollution, the advantages of cheap price . And it adopts the elevated way, taking up a small amount of arable land. Maglev trains mean that these trains use the basic principles of magnets to float on rails instead of the old steel wheels and rail trains. Magnetic levitation utilizes the electromagnetism of the magnet to lift the entire train compartment away from nasty friction and unpleasant clangtones to achieve a rapid "fly" without contact with the ground or fuel.

Maglev trains are the most fundamental breakthrough in railroad technology since Stephenson's "Rocket" steam locomotive was introduced about 200 years ago. Maglev train seems to be still a novelty today, in fact, its theoretical preparation has a long history. Maglev research originated in Germany. As early as 1922 German engineer Hermann Kempel proposed the principle of electromagnetic levitation on magnets and applied for a patent on magnet levitation trains in 1934. Since the 1970s, with the continuous strengthening of the economic strength of the industrialized countries in the world and the need of enhancing their transport capacity to meet the needs of their economic development, developed countries such as Germany, Japan, the United States, Canada, France, and Britain have successively begun to plan their projects in the maglev transport system Development.
