Superconducting Levitation Superconductors expel magnetic field, and hence repel magnets. This repulsion can be stronger than gravity, which leads to levitation - the most fascinating manifestation of superconductivity. This web-page presents a few movies showing how the superconducting levitation works. AVI movie 280 Kb MPEG movie 330 Kb QuickTime movie 460 Kb. Movie 1: Levitation in action A superconductor is immersed in liquid nitrogen to provide cooling below the critical temperature. A magnet is placed in the air above the superconductor and left there levitating. Nothing but magnetic interaction keeps the magnet from falling down. AVI movie 420 Kb MPEG movie 360 Kb QuickTime movie 850 Kb. Movie 2: Finding a better levitating position The levitating magnet has a preferential position above the superconductor and returns there after a small perturbation by a human finger. When the magnet is pushed hard towards the superconductor, it changes the magnetic field distribution in the superconductor, and a new position becomes preferential.

back to list magnetic levitation of trains Q: necesito realizar la levitacion magnetica de un tren puedes ayudarme (I need to understand the magnetic levitation of a train. Can you help me?) leynel altuve (age 17) divercificado caracas venezuela A: In the future, maglev trains might be an option as a mode of transportation. In the structure of the track, there is a magnetized coil, called a guideway, that runs along the track and repels the large magnets on the train's undercarriage. This repelling force raises the train to about .39 to 3.93 inches above the guideway. When the train is raised, magnetic fields are created by the power supplied to the coils within the guideway walls; these magnetic fields pull and push the train along the guideway. The electric current is changing in polarity because they are continuously alternating in the coils, and this change in polarity causes the magnetic field in front of the train to pull the train at amazing speeds. Also, the magnetic levitation train can travel without friction because it rests above the guideway, with a layer of air in between, to achieve speeds at 310 miles per hour.

Experiments with magnetic levitation Diamagnetic Levitation This is an experiment where a magnet will float between two diamagnetic plates. No electromagnets are needed, no sensors are needed, no current source is needed. Only one other magnet is needed to help balance the force of gravity. The fixture seen here was purchased from www.magnetlevitation.com and is a very well assembled and thought out demonstrator of diamagnetic levitation. As you remember, diamagnetism is a property of some materials where they repel magnetic fields, both North and South poles. Is it possible to make a magnet float on top of a diamagnetic piece of material? Is it possible to make a piece of diamagnetic material float on top of a magnet? The answer is YES to both of these questions. With this fixture, we have a magnet that will float between two pieces of pyrolytic graphite , a fairly good diamagnetic material. If it is too close to the graphite on the bottom, it will rise. If it is too close to the graphite on the top, it will drop. Eventually, it will find a happy mid-point where it will hover, or levitate, stably . Since the magnet is a bit heavy, though, a

For example, a short-distance maglev shuttle operated for 11 years from 1984 to 1995 between the Birmingham, England, airport and the city train station. However, the greatest worldwide interest is in high-speed maglev systems. Train speeds of 552 km/h (343 mph) have been demonstrated by a full-size maglev vehicle in Japan, while in Germany a maglev train has run at 450 km/h (280 mph) and in China a maglev train has reached a peak speed of 432 km/h (268 mph).

Tech Home Activities Projects Cool Web Sites ... Pueblo Home 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 electro dynamic 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

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.

Ed Phillips' Magnetic Levitation A discussion of magnetic levitation began on July 31, 1999, on the SciClub mailing list with this message from list owner William Beaty ( billb@eskimo.com Hey, SCIENCE NEWS has a brief article on a new form of magnetic levitation. See the 7/24/1999 issue, where a neodymium magnet is levitated between finger and thumb! It's done by lifting a small, powerful permanent magnet using a much larger magnet far above. In the article the authors used a huge electromagnet 8 ft. above the little neo. magnet. They also mention that a "handheld" version exists, so a huge magnet is probably not a requirement. But this doesn't produce stable levitation. So, they place a piece of weakly diamagnetic material above the small magnet, and this repels it downwards. Gravity pulls down, the strong attraction of the huge magnet pulls up, and the weak repulsion from the diamagnet pushes down. With a low-gradient field from a large magnet, the strange repulsion profile of the diamagnet forms an energy well, and the magnet hangs in space. Even the weak repulsion of human fingers is enough to stabilize the hovering magnet! I tried this by lifting a 1/2" neo. disk magnet using a large stack of similar magnets, but unfortunately the temperature of the little disk-magnet messes everything up. If the magnet is warmed by my hands, it attracts less strongly, and if it cools a bit, it flies upwards immediately.
