    Extractions: Magnetic levitation using a superconductor is one of the most dramatic physics experiments ever. Amazingly, we found a small manufacturer of superconducting pellets right here in town. You can purchase this kit on our Web Shopping Cart . The kit includes 1 superconducting ceramic disc, about 1" diameter, an excellent instruction manual, a convenient styrofoam container(good for holding liquid nitrogen during the demonstration), 1 pair of plastic tweezers, and one 3/16" NdFeB magnet. In order to make this work you'll need to get your own liquid Nitrogen. This must be obtained locally. Of course, even high temperature superconductors need to be very cold. Liquid Nitrogen is required to chill the supeconductor to its critical tempurature. Surprisingly, liquid Nitrogen is very easy to come by. It is has many common applications, and is widely available and inexpensive. Any supply shop that sells CO2 and welding gasses should have it. Although special containers are made for the safe storage/shipment of liquid Nitrogen, many shops will be more than happy to fill your stainless steel thermos bottle for a couple bucks. It's very important, if you acquire some in a thermos bottle, or other container that you understand the dangers and safe handling procedures. You do not want liquid Nitrogen to come into contact with your body!

64. Magnetic Levitation
    To cause diamagnetic levitation, both the diamagnetic material and magnetic material must produce a combined repulsive force to overcome the force of gravity.  
    http://www.rare-earth-magnets.com/magnet_university/magnetic_levitation.htm
    
    Extractions: Up Diamagnetism A diamagnetic substance is one whose atoms have no permanent magnetic dipole moment. When an external magnetic field is applied to a diamagnetic substance such as bismuth or silver a weak magnetic dipole moment is induced in the direction opposite the applied field. All materials are actually diamagnetic, in that a weak repulsive force is generated by in a magnetic field by the current of the orbiting electron. Some materials, however, have stronger paramagnetic qualities that overcome their natural diamagnetic qualities. These paramagnetic materials, such as iron and nickel, have unpaired electrons. Some Diamagnetic Elements Some Ferromagnetic Elements Some Paramagnetic Elements Diamagnetic Levitation Diamagnetic Levitation occurs by bringing a diamagnetic material in close proximity to material that produces a magnetic field. The diamagnetic material will repel the material producing the magnetic field. Generally, however, this repulsive force is not strong enough to overcome the force of gravity on the Earth's surface. To cause diamagnetic levitation, both the diamagnetic material and magnetic material must produce a combined repulsive force to overcome the force of gravity. There are a number of ways to achieve this: Placing Diamagnetic Material in Strong Electromagnetic Fields Modern Electromagnets are capable of producing extremely strong magnetic fields. These electromagnets have been used to levitate many diamagnetic materials including weekly diamagnetic materials such as organic matter. A popular educational demonstration involves the placement of small frogs into a strong static electromagnetic field. The frog, being composed of primarily water, acts as a week diamagnet and is levitated.

    http://www.raven1.net/flotfrog.htm
    
    Extractions: Site Index Page Asked to think of an animal that can fly, most people don't picture a frog. Nonetheless, in April 1997, a team of British and Dutch researchers announced success in lavitating a live frog by using a powerful magnet. According to one of the human observers, the frog emerged from the flight unharmed and "happily joined" his fellow frogs in a biology department. The amusing video image of the frog hovering in midair circulated widely and captured many people's fancy.... [snip] The seeming ability to defy gravity is what delights most people, but the demonstration highlights a more subtle idea that is often overlooked in everyday life - that many objects considered nonmagnetic do, in fact, possess magnetic properties. The water, proteins, and organic molecules that make up frogs and other living things are diamagnetic, which means that in the presence of a magnetic field, they become weakly magnetized in such a way as to oppose the applied field. Diamagnetism is what allowed the researchers to float the frog. Scientists are now looking into this phenomenon to simulate zero gravity and thus provide a low-cost substitute for experiments now possible only in outer space. They plan to tease out how the absence of gravity affects biological systems, especially developing embryos.

    Extractions: Understanding Introduction The basics Understanding Jorcarna Light Theory Conclusion Magnetic Circuit ... New Beginning Making of Jorcarna IF we put two repelling magnets inside a none magnetic tube then it is feasibly possible to levitate the top magnet with a fixed load on top of the top magnet. The tube is needed as a guide because both magnets are being bombarded by magnetic flux in all directions thus stopping the magnets repelling sideways or flipping over to then attract each other. At this stage it is important to note, that the magnetic flux repel only on the solid magnets to create levitation and pass through the non magnetic tube.The purpose of this exercise is to prove that a repelling magnetic field has levitation capabilities all be it we are using two separate platforms the base of the tube (ground)and the free moving levitated magnet. Much the same using the man in the picture pushing a wheelbarrow he and the barrow as one structure and the ground to push off is the other structure. But what JORCARNA can do is push one structure from within the same structure defying Newton`s third law.

    Extractions: drawHeader('4', 'FFC800', 'image_superconductivity.jpg', 'superconductivity', ''); Levitation experiments enabled by Oxford Instruments Radical superconducting magnet helps scientists bend the rules of gravity A new type of high field superconducting magnet from Oxford Instruments has enabled physicists at the University of Nottingham to balance the force of gravity and levitate heavy and dense materials such as lead, gold and diamonds. The patented Minimum Condensed Volume™ (MCV™) Cryofree™ superconducting magnet, developed and manufactured by Oxford Instruments in collaboration with the University of Nottingham, is the first of its kind in the world. Unlike conventional superconducting magnets, the MCV magnet never needs to be refilled with liquid helium and yet can generate a field over 300,000 times stronger than the Earth’s magnetic field. The magnet is also designed with a much shorter bore than standard versions that is maintained at room temperature. "This makes the magnet very easy to use and ideal to study the effects of simulated zero-gravity conditions on growing seedlings, for example - research which has relevance to future manned space exploration," said Professor Laurence Eaves, Nottingham. The Nottingham team have published their findings in the latest issue of Nature . The experiment is based on the magneto-Archimedes effect, using cold (100 K) oxygen gas in the magnetic field to levitate objects, such as diamonds, that are dense enough to sink in water. Magnetised liquid oxygen provides even greater buoyancy up to 340 times that of water, enabling even heavy metals, such as gold and platinum, to be levitated.

Despite frequent delays, airplanes still provide the fastest way to travel hundreds or thousands of miles. Passenger air travel revolutionized the transportation industry in the last century, letting people traverse great distances in a matter of hours instead of days or weeks. The only alternatives to airplanes feet, cars, buses, boats and conventional trains are just too slow for today's fast-paced society. However, there is a new form of transportation on the horizon that will revolutionize transportation of the 21st century the way airplanes did in the 20th century.

    Extractions: BACKGROUND The Subcommittee will conduct a hearing to examine magnetic levitation transportation issues. Magnetic levitation (maglev) is an advanced technology in which magnetic forces lift, propel, and guide a vehicle over a guideway. Utilizing state-of-the-art electric power and control systems, this configuration eliminates contact between vehicle and guideway. Maglev systems, although not yet in revenue service, have been demonstrated to operate at speeds around 300 miles per hour (mph). High-speed passenger trains such as the European TGV and ICE systems, using flanged wheels and steel rails, have also reached speeds approaching the 300 mph level on dedicated rights-of-way. Because of its high acceleration and cruising speed, maglev offers competitive trip-time savings to auto and aviation modes in the 40 to 600-mile travel markets. By comparison, current U.S. passenger trains such as the Amtrak Metroliners operate at up to 125 mph on parts of the Northeast Corridor. The new Acela high-speed trains used by Amtrak are capable of 150 mph, but in most areas except the newly electrified New Haven-Boston segment of the Northeast Corridor, they are limited to about 130 mph by the infrastructure. The Maglev Deployment Program in TEA 21 In 1998 Congress passed the "Transportation Equity Act for the 21st Century" (TEA 21), which created a National Magnetic Levitation Transportation Technology Deployment Program. The program is to demonstrate high-speed maglev technology in commercial service through a project of about 40 miles in length.

    Extractions: The pluses of such an approach are two-fold: first of all, a completely "levitated" base will completely decouple the HiFi component from the HiFi rack or table, minimizing vibrations by contact. Secondly, the idea of levitation has always fascinated scientists and techno-minded researchers since it reminded one of the greatest man's dreams: to fly. Sadly, the task isn't all that easy: first of all a full magnetic levitation with passive magnets isn't easy to achieve (actually it's impossible, see later) because the suspended base tries to escape from the equilibrium position with apparent no reason, secondly you need strong magnets and, hence, magnetic fields. These may be not welcomed near phono cartridges, phono stages and CD players, for example.

    Extractions: Lesson for December 26, 2000 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.

    Extractions: MAGNETISM Magnetism brings to mind horseshoe magnets and iron filings. However, magnetism is very closely related to electricity. In 1819 the Danish physicist and chemist, Hans Christian Oersted (1777-1851), during a lecture demonstration, observed that an electric current can affect a magnetic compass needle and thus united what until then had been viewed as two distinct subjects[1]. The electric motor is the modern implementation of this phenomenon. In the 1820's Michael Faraday (1791-1867) in England and Joseph Henry (1797-1878) in the United States independently demonstrated that a time-varying magnetic field can produce an electric current. Electric generators and eventually a world dominated by electronics was the result. The same discovery was previously made in 1802 by an Italian jurist, Gian Dominico Romognosi, but was overlooked because it was published in a newspaper, Gazetta de Trentino , rather than in a scholarly journal. 1.
