Magnetic Levitation Train is a type of train that uses electromagnetic system for both levitation and propulsion. The maglev transportation idea has been around since 1941 when German engineers had patented the idea to build a transportation system using magnetic levitation. However, the first commercial maglev was built in Shanghai, China in 2004 where it services between the city’s international airport to the outskirt Pundong. The track covers about 18 miles and runs up to 500 miles per hours (Hall1). The maglev train system provides an alternative concept when comparing to its older train system as the maglev train neither has wheels nor engine. In which it can provide an incredible rate of speed due to an extremely low friction that the …show more content…
These trains heavily rely on his tracks since the tracks does all physical lift and propulsion. Each train has superconductive magnets in which makes contact with the rail has electrical coils (Hall 1). Thus develops an electromagnetic force. However, there a few different methods how these train operates. At the moment, there are two most well-known methods which is electromagnetic suspension (EMS) and electrodynamic suspension (EDS).
The electromagnetic suspension’s main idea to use electrical currents to move the train (Hall 1). It follows Faraday’s and Lenz’s law to create a magnetic field to create a desirable repulsion effect. During in-class, Faraday’s law is the magnitude of the induced emf in a circuit while Lenz’s law is the direction opposite of induced current or emf). In order to create the motion of train, engineers make a base

The main idea of electrodynamic is the concept of diamagnetism. In class, diamagnetism is the property of an object which causes it to create a magnetic field in opposition to an external applied magnetic field in which creates repulsion (Pathak 6). Diamagnetism is when the total net electron is equal to zero as the orbitals are fully paired with electrons. Although the electrons are paired, the magnetic effects are in present. The reason is the external field alters the orbital velocity of electrons as random magnetic dipole moment. Also, it has a small relative permeability in which it will not change the material magnetization. However, the flaw of diamagnetism is that it has a weak effect in most material when a substance applies to an external magnetic field. On the other hand, a superconductor is another type of diamagnetism but with additional property of expelling magnetic fields. Also, superconductor magnets provide a stronger effect on external magnetic field than a diamagnetic
