“Neither a wise man nor a brave man lies down on the tracks of history to wait for the train of the future to run over him,”- President Dwight D. Eisenhower. Maglev is a new type of train that uses magnets to levitate above the track and reduce friction. Maglev can go up to a speed of 310 mph (500 km/h) allowing people to travel on land much faster than before. The researcher will create a model Maglev and see which system, EMS or EDS, will result in better efficiency. Efficiency will be measured by the ratio of weight of train to the time to cross the track. If EMS weighs more but is faster while EDS weighs less but more to operate, than EMS should result in better efficiency because the train will weigh less.

How Maglev Works
Electromagnetic Suspension (EMS)
Electromagnets are magnets that can be turned on and off with electricity. There is a big power source, metal coils in the track and magnets under the carts. The Maglev does not have an engine but is propelled by magnets in the track, called a guideway. Magnets in the guideway, repel the magnets in the train causing it to levitate between 1 to 10 cm. The magnets in front of the train are turned to pull the train while the magnets behind the train push it. Since the train is levitating, the friction is taken away and can cause the train to go up to speeds up to 500 km/h (310 mph).

A German company called Transrapid uses Electrodynamic Suspension (EMS). The bottom of the train wraps around the track and levitating it at 1 cm. Transrapid has shown that this system can cause the train to go 300 mph with people on board.

Electrodynamic Suspension (EDS)
Japan uses a system called Electrodynamic Suspension (EDS). It uses super-cooled superconducting magnets that ar...

The fastest speed of a passenger train is 350 km/h while the the Shanghai Maglev can reach up to speeds of 430 km/h
Maglevs are not used for inner-city transportation yet, but hopefully soon.

The Shanghai Maglev train cost 1.2 billion dollars.
It took 1.5 years to build the 30.5 km track.
It takes the train about 15-20 minutes to complete its journey.

Maglev Trains Essay example

- Maglev Trains As almost any child knows, magnets have the ability to attract and repel other magnets. This knowledge is now being utilized in separate projects in Germany and Japan to propel and levitate a new and innovative type of train, the magnetic lift train. A German company called Transrapid is now able to build a train takes advantage of a magnets ability to attract magnetic materials. Upon observing the system from a distance, it looks to be composed of only T-shaped track and a train that wraps around the ledges of the track....   [tags: Magnet Train Trains Essays]

The Benefits of Maglev Trains Essay

- Transportation is one of the most essential spheres of human’s life, hence, it is very important for it to have minimal effect on the environment, be safe, cheap, comfortable, and fast in use. Conventional transport, such as trains and airplanes, causes a number of problems including air pollution, high amounts of energy consumption, huge need of maintenance, high prices, and risks of safety, thus not being efficient enough. Therefore, new generation of transport must correspond to definite requirements: be efficient, reliable, and environmentally sound....   [tags: environment, energy consumption]

Maglev Research Essay

- Maglev Research Studies show that people are reluctant to abandon automobile use for trips of less than 100 miles, while planes are most efficient at trips of over 500 or 600 miles. The trips in between these distances are those that will be best served by magnetic levitation (Maglev) transportation systems. By replacing short, inefficient commuter flights between cities, maglev trains might eventually link sections of the country, ease traffic congestion on the highways, and help alleviate overcrowding at airports....   [tags: Papers]

Maglev Trains And The Technology Behind Them Essay

- Maglev Trains And The Technology Behind Them Introduction Magnets Magnetism is a phenomenon that occurs when a moving charge exerts a force on other moving charges. The magnetic force caused by these moving charges sets up a field which in turn exerts a force on other moving charges. This magnetic field is found to be perpendicular to the velocity of the current. The force of the field decays with distance from the charge. Most magnets we come across are weak permanent magnets, such as fridge magnets and door catches....   [tags: Papers]

Mag Lev Trains Essay

- The basic concept of how a magnetic train works is very simple. The train has magnets all along the underbody. Each magnet is faced the exact same way, with the poles all facing the same direction. As you know from playing with magnets, opposites attract and alike kinds always want to push away. The track which the train rides on is lined with these magnets, with alike poles facing the train. This creates an air cushion between the train and the track. Forward motion of these magnetic trains, resides on the magnetic propultion of the track....   [tags: Magnetic Magnet Train ]

Khushwant Singh's Train to Pakistan Essay

- Frantz Fanon (1925-1961) is a renowned postcolonial thinker known for his two seminal works Black Skin and White Masks (1986) and The Wretched of the Earth (1991). The latter is a paean on the cult of vociferous revolution and it unravels how anticolonial sentiments may address the venture of decolonization. Fanon delves at length how ill equipped are the former colonies to function as independent nations and proffers an excoriating criticism on present day bourgeois nationalism in third world nations....   [tags: Train to Pakistan Essays]

Maglev Consequences Essay

- Maglev Consequences Magnetically levitated ground transportation, or "maglev," is an advanced mode of surface high speed transportation whereby a vehicle gliding above a guide track is suspended, guided, and propelled by magnetic forces. Because they never touch the guide track causing friction, maglev vehicles can be designed to travel at extremely high speeds, 500 kilometers per hour (300 miles per hour), or more. Americans traveled 3.2 trillion passenger kilometers (2 trillion passenger miles) by car, truck, bus, and public transit, and 9.8 billion passenger kilometers (6.1 billion passenger miles) on Amtrak....   [tags: essays research papers]
