![]() He dreamed up the idea of using superconducting magnets to levitate a train car. The idea came to Powell as he sat in a traffic jam, thinking that there must be a better way to travel on land than cars or traditional trains. James Powell and Gordon Danby of Brookhaven received the first patent for a magnetically levitated train design in the late 1960s. Maglev - short for magnetic levitation - trains can trace their roots to technology pioneered at Brookhaven National Laboratory. Unlike conventional trains which rely extensively on internal combustion engines, MAGLEV trains rely on electromagnets for propulsion.What if you could travel from New York to Los Angeles in just under seven hours without boarding a plane? It could be possible on a Maglev train. A typical MAGLEV train works on the principle of “magnetic levitation”. ![]() This very requirement gave birth to “MAGLEV trains”. Therefore we need to design a rail system which can achieve high speeds to reduce the duration of travelling of commuters without affecting the reliability. ![]() Although railways have proved to be the most reliable mode of transportation, it takes a back seat when it comes to high speed travel. As the world knows, railways have been extensively used for quite some time now. When we hear the words “transportation” and “reliability” a picture of Train appears in our mind. This calls for a potent transportation system with high performance and high reliability. People want to travel farther and faster these days. In the modern era there is a saying – “Life runs on wheels” which is very much true. Transportation has become an integral part of our lives. This paper gives an idea about the tech aspects of maglev projects worldwide such as Germany, Japan, and USA and also discusses about various idea to bring Maglev trains in developing countries like India. The magnetic levitation system used by these trains play an important role in suspending the Maglev train stably and following the track quickly with the adequate gap from the side walls thus highly reducing chances of damage. This has a lot of potentials to create trains that require a high initial investment but later on low maintenance and helps in fast transportation thus saving time. Electromagnets and superconducting magnets have allowed us to create a magnetic levitating train nicknamed "Maglev" which reduces friction between track and train by floating over it instead of directly being in contact. This problem can be solved by the concept of electromagnetism. In this growing world when cities and towns continue to become more crowded, the modes of transportation that are currently available to us will not be able to handle the demands of these overpopulated areas. The concept is easy but the techniques and design are complex. Therefore for passenger safety, protection is needed, which can increase the weight of the train. The effect of a strong magnetic field is unknown to many. A very strong magnetic field is needed to lift a heavy train. Electromagnetic fields also affect the design of the train. Magnetic mining using electromagnets or permanent magnets is unstable because of Earnshaw's theory Diamagnetics and superconductivity magnets can sustain maglev stably. In a design, the train can be lifted by a magnetic repulsive force and can travel with a linear motor. Japan and Germany are two countries that are active in developing maglev technology to produce many approaches and designs. most recently, it may be more economical, using a permanent magnet (Inductrack).depending on controlled electromagnetic (electromagnetic suspension) or who.depends on superconductivity magnets (electrodynamic suspensions).Technology There are three types of maglev technology: Due to the high cost of magnetic rail making, in the world in 2015 there were only two Maglev lines opened for public transportation, namely Shanghai Transrapid in China and Linimo in Japan. Some countries that have developed this type of train are China, Japan, France, America and Germany. With the small friction force and magnitude of thrust, the train is capable of traveling at speeds of up to 600 km / h, much faster than ordinary trains. Maglev trains also use magnets as a booster. As the name suggests, the principle of this train is to use the magnetic force to lift the train so that it floats, not touching the rail so that friction can be reduced. Maglev trains (short for magnetically levitated trains, in Indonesian called magnetic levitation trains) are a type of magnetic floating train.
