SEARCH STORIES: Navigation Magnetic Levitation The Osgood File (CBS Radio Network): 9/7/04, 1/24/05 New high-speed trains without rails or wheels go 300 mph. A new high-speed train in Shanghai, China, hurtles up to 450 passengers along at more than 270 mph as they race from the financial district to its airport, about 20 miles away. By taxi the trip takes 55 minutes, but the high-speed line cuts the trip to less than 8 minutes. The fast train employs a system called Magnetic Levitation (or maglev) where its cars literally float above the track. There's no rails or wheels and no on-board motor to weigh it down. Instead, the system uses the attractive forces between electronically controlled magnets to raise the train about six inches above its guideway. The support magnets pull the vehicle up to the guideway from below while the guidance magnets keep it laterally in line. Dr. Richard Thornton, CEO of Magnemotion and widely regarded as an expert in the field of maglev technology, says that if you have steel wheels rotating they create aerodynamic drag and friction. According to Larry Blow of Transrapid International – the German company that built the Shanghai project – despite traveling at speeds up to 310 mph, the maglev system runs more quietly than a typical commuter train traveling at lower speeds, consumes less energy and is nearly impossible to derail because of the way the train's underside partially wraps around the guideway, like a giant set of arms hugging the train to the elevated platform. Blow says that the only thing needed is money he is hopes that the federal Highway Bill will provide funding for construction.

Magnetic Levitation Vehicles Introduction As we move toward the twenty first century, an analysis of our transportation needs indicates that the systems we have in place today may not be capable of supporting our transportation needs for the future. Because of the growing need for quicker and more efficient methods for moving people and goods, researchers have turned to a new technique, one using electromagnetic rails and trains. This rail system is referred to as magnetic levitation , or maglev . Maglev is a generic term for any transportation system in which vehicles are suspended and guided by magnetic forces. Instead of engines, maglev vehicles use electromagnetism to levitate (raise) and propel the vehicle. Alternating current creates a magnetic field that pushes and pulls the vehicle and keeps it above the support structure, called a guide way There are two basic types of maglev - electromagnetic suspension (EMS) and electrodynamic suspension (EDS) EMS depends on attractive force . Electromagnets on the vehicle are drawn toward a pair of steel rails. Most of the vehicle rides above the rails but the magnets wrap beneath the rail. As the magnets pull the vehicle upward, their current is electromagnetically regulated to maintain a constant gap between the rails and the vehicle. EDS , on the other hand, is based on repulsive force . The vehicle contains superconducting magnets that induce a repulsive force in a conducting guide way as the vehicle moves along it. Superconducting electromagnets

THE REVOLUTIONARY DUALMODE TRANSPORTATION SYSTEM Chapter 9 Magnetic Levitation and Propulsion LEVITATION ISN’T JUST A MAGIC TRICK If it were magic, magnetic levitation would be a good trick because the vehicles it levitates are a lot heavier than is the magician’s beautiful assistant. Repulsion maglev was first proposed by US rocket scientist Robert Goddard, and described in the November 1909 issue of SCIENTIFIC AMERICAN . It took us a half-century to use Goddard’s rocket inventions, and it will be over a full century before we will use his magnetic-levitation inventions significantly. Magnetic levitation (maglev) is a well-developed and tested modern technology. It is practical, efficient, safe, quiet, and economically sound. It has already carried a total of over two and two-thirds million paying train passengers in Japan, Canada, and Germany, without an accident (a safety record railroad tracks could never meet.) In October 1993 the Transrapid 07 maglev train ran 279mph at Emsland, Germany. Another type of maglev train, the ML-500 ran at 343 miles per hour in Japan on April 14, 1999. The American Maglev Star train, which is being proposed for installation between the Kennedy Space Center and Cape Canaveral, is planned for speeds up to 350 mph. Another maglev train recently went into operation at Shanghai, China. But all is not rosy in the railroad business. In recent years a number of maglev trains have been planned then cancelled. As we saw in the previous chapter, coupled trains have major disadvantages that make that concept largely obsolete whether the cars are supported by steel wheels on rails or by maglev. For that reason conventional railroads are dying and I predict that maglev trains will also die.

31. Technical Page - Maglev Monorail Introduction In 1922, Hermann Kemper in Germany pioneered attractivemode (EMS) Maglev and received a patent for magnetic levitation of trains in 1934. http://www.monorails.org/tMspages/TPMagIntro.html

Introduction to Maglev Monorail There are 2 basic types of non-contact Maglev systems (we will discuss propulsion later): Electro Dynamic Suspension (EDS) , and Electro Magnetic Suspension (EMS) . EDS is commonly know as "Repulsive Levitation," and EMS is commonly known as "Attractive Levitation." A Brief History of Magnetic Levitation In the early 1900s, Emile Bachelet first conceived of a magnetic suspension using repulsive forces generated by alternating currents. Bachelet's ideas for EDS remained dormant until the 1960s when superconducting magnets became available, because his concept used too much power for conventional conductors. In 1922, Hermann Kemper in Germany pioneered attractive-mode (EMS) Maglev and received a patent for magnetic levitation of trains in 1934. In 1939-43, the Germans first worked on a real train at the ATE in Goettingen. The basic design for pratical attractive-mode maglev was presented by Kemper in 1953. The Transrapid (TR01) was built in 1969. In 1969, groups from Stanford, Atomics International and Sandia developed a continuous-sheet guideway (CSG) concept. In this system, the moving magnetic fields of the vehicle magnets induce currents in a continuous sheet of conducting material such as aluminum. Several groups, including MIT (Kolm and Thornton, MIT, 1972,) built 1/25th scale models and tested them at speeds up to 27 m/s (97.2 km/h.) The CSG concept is alive and well in 2001 with the Magplane. EDS systems were also being developed in the US in the early '70s, including work by Rohr, Boeing, and Carnegie-Mellon University. Maglev research in the US came to a screeching halt in 1975 when the Federal government cut off the funds to HGST research.

Tech-FAQ Enter your search terms Submit search form Web www.tech-faq.com FAQs Tutorials Web Tools Reference ... + Miscellaneous What is Magnetic Levitation? Magnets are mainly characterized for having poles: if you put together poles of the same charge they repel and if you put together charges of different pole, they attract. A body will be under Magnetic Levitation when it floats due to that special repelling quality of the magnets, i.e. when the force generated by the electromagnetic repulsion is strong enough to balance the weight of the object. Methods for Obtaining Magnetic Levitation There are different methods for obtaining Magnetic Levitation. For heavy objects, the main are electromagnetic suspension and electrodynamic suspension. See: How does a Maglev Train work? for more details. It has been proved that the levitation cannot be stable under static magnetism; there are several ways to overcome this problem, the use of diamagnetic materials is one. Diamagnetic substances repel the magnetic field; this effect can be used to create levitation of light objects. In particular superconducting substances are perfect diamagnets, allowing the lift of heavier weights. Another mechanism is the use of eletrodynamic fields. Moving charges produce magnetism and moving magnets produce electricity; that is why both phenomena have been unified under the concept of electromagnetic field. Different arrays of moving conductors and/or magnets can be created to generate the stable vertical push needed for levitation.

The combined threats of Peak Oil and global warming Magnetic levitation uses the repelling properties of magnets to lift an object off the ground. In this case, the object is a wind-harvesting fan. The benefit of having it floating in midair is that it cuts down on the friction that causes so much inefficiency in the traditional windmill-style wind energy harvester we see dotting our coastlines. Friction is also the key factor necessitating frequent maintenance of windmill turbines, adding considerably to the cost of running them. Without rotational friction to overcome, a wind turbine generator can begin to harvest power from air speeds as low as 1.5 meters per second.

Weekly Online Lesson Online Lesson Archive Grade Level: 7-12 Subject: Physical Science Magnetic Levitation Train Shanghai, China may be the world's first city to build a commercial magnetic levitation train. German consortium Transrapid is pursuing the contract to build the controversial "Maglev" high-speed train. Germany has invested decades of research and billions of dollars into developing Maglev technology, as has Japan, though the technology has yet to be put to commercial use. Maglev uses powerful magnets to hold a train a few millimeters from the track and propel it with little noise or vibration. In an April time trial, a Japanese test Maglev set a speed record of 343 mph. Germany has its own test Maglev, which a delighted Chinese Premier Zhu Rongji rode in July. Shanghai is expected to sign a contract with Transrapid as early as December, 2000 for a 20- to 25-mile line to the 1-year-old Shanghai Pudong International Airport. The venture could cost more than $1 billion. This week's online lesson is about magnets, magnetism, and Maglev technology.

37. Magnetic Levitation When you are interested to perform a series of (pilot) studies using the levitation magnet you are invited to contact us and discuss various possibilities. http://www.desc.med.vu.nl/Magnet_us.htm

Magnetic levitation Every element (in the periodic system) is magnetic. However, there are three main levels or domains of magnetism. The smallest effect is know as diamagnetism and is a property of elements like antimony, bismuth, copper, carbon but also phosphorus and hydrogen. Paramagnetism has an intermediate value, about two orders of magnitude higher than diamagnetism. Paramagnetism is seen in e.g. aluminum, zinc, liquid oxygen but also in glass and rubber. The largest magnetic effect is known as ferromagnetism. This is, in our daily life, the most common form of magnetism. The only elements with ferromagnetic properties are iron, cobalt, and nickel. Ferromagnetism is about 10 times larger compared to diamagnetism. Ferro and paramagnetic elements may easily be levitated in low gradient magnetic fields. This system is used in various commercial products. To elevate diamagnetic materials, however, much higher field strengths and field gradients are necessary. In such a high power magnet organic materials or even living biological samples may be elevated, thereby counteracting the force of gravity. Although the various systems have their specific limitations, for some small samples this microweight 'simulation' may be used to study living samples in preparation of a real microweight experiment.

Chapter 8: Barry's Magnetic Levitation Chapter 7: Coilgun Mark I Home Site Map Chapter 9: Visual Levitation These coilguns with control circuits are great! Now... How can you use them for magnetic levitation This is slightly off-topic from coilguns, but magnetic levitation has many common design principles and is a little easier to build! How Levitation Works If you hold two permanent magnets close together, you see that one of them will jump strongly toward (or away) from the other. In 1842, Samuel Earnshaw expressed the perversity of inanimate magnetic objects in his theorem. It explains this frustrating behavior will always prevent you from suspending one permanent magnet above or below another, no matter how one arranges the two magnets. However, an active control circuit can get around this problem by rapidly adjusting the magnet's strength. The general principle is straight forward: An electromagnet pulls a ball upward while a light beam measures the exact position of the ball's top edge. The magnet's lifting force is adjusted according to position. As less light is detected, the circuit reduces the electromagnet's current. With less current, the lifting effect is weaker and the ball can move downward until the light beam is less blocked. Voila! The ball stays centered on the detector! It is a small distance across the photodetector, perhaps a millimeter or two, but this is sufficient to measure small changes in position. Of course, if the ball is removed the coil runs at full power. And conversely, if the light beam is blocked the coil is turned completely off.
