    High speed magnetically levitated ground transportation is a new surface mode of transportation, in which vehicles glide above their guide ways, suspended, glided and propelled by magnetic force. with which stable and contactless suspension between a magnet (magnetic body) and a fixed superconducting magnet, displaces laterally from. train set surpassed the speed record of the three-car train set, attaining a maximum speed of km/h in a manned vehicle run. In March , the Maglev Practical Technology Evaluation Committee of the Ministry of Transport of Japan concluded, "the JR-Maglev has the practicability for ultra high speed mass transportation system".

    The magnetized coil running along the track, called a guideway, repels the large magnets on the train's undercarriage, allowing the train to levitate between and inches (1 to 10 centimeters) above the guideway [source: Boslaugh].Once the train is levitated, power is supplied to the coils within the guideway walls to create a unique system of magnetic fields that pull and push the. A REBCO magnet has been developed for the electromagnetic vibration test of the ground coils for the maglev. The ground coils receive vibration force when a maglev vehicle passes through. That vibration force can be reproduced by exciting the ground coil by combination of AC and DC in the high magnetic field of the superconducting magnet.

    Maglev (derived from magnetic levitation) is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track, and another set to move the elevated train ahead, taking advantage of the lack of certain "medium-range" routes (usually to km [ to mi]), maglev can compete favorably with high-speed rail and airplanes. systems. Active magnetic suspension, on the other hand, seems to merit further study for urban applications. Superconducting magnet suspen- sions are suggested as worth closer definition for high speed ground transportation.. 1. INTRODUCTION.

The superconducting magnetically levitated transport (Maglev) system is conceptualized as a next-generation high-speed transportation system.

For practical use, it is important to achieve adequate ride comfort particularly in high-speed running. Magnetic levitation (maglev) is a relatively new transportation technology in which non-contacting vehicles travel safely at speeds of to miles-per-hour or higher while suspended, guided, and propelled above a guideway by magnetic fields.

The guideway is the physical structure along which maglev vehicles are levitated. Various guideway configurations, e.g., T-shaped, U-shaped, Y. The superconducting magnetically levitated transport (Maglev) system is a focus of interest as a future mode of transport at high speeds of over km/h.

The magnet can also be used for suspension of vehicles in high-speed ground transportation systems. A superconducting magnet was built for probing the electromagnetic interaction of strong magnetic fields and moving current conductors.

Abstract A program to develop a prototype of a magnetically levitated (maglev) high-speed-ground-transportation system has been announced by the U.S. administration. This paper reviews the development of maglev and steel-wheel-on-steel-rail trains and examines the unique right-of-way requirements for these systems.The power needed for levitation is usually not a particularly large percentage of the overall consumption; most of the power used is needed to overcome air drag, as with any other high speed train.

The highest recorded speed of a Maglev train is kilometres per hour ( mph), achieved in Japan in6 kilometres per hour ( mph) faster.The SCMaglev (superconducting maglev, formerly called the MLU) is a magnetic levitation railway system developed by Central Japan Railway Company (JR Central) and the Railway Technical Research Institute.
