    Extractions: - Benjamin Franklin What is Maglev? Mag netic Lev itation Transport, or maglev, is a revolutionary form of railway transport. It uses magnetic forces to make the vehicles hover above the track rather than running along them, thus reducing the friction between the two and allowing much higher speeds to be attained than are safely achievable on any other form of ground based public transport. A Brief History of the Technology Though the idea of high speed trains levitated by magnetic forces seems revolutionary, even to us today, the concept is over a century old. In the early 1900s, Bachelet in France and Goddard in the United States discussed the possibility of using magnetically levitated vehicles for high speed transport. However, they were unable to propose a practical way to achieve this goal.

    Extractions: Cool Experiments with Magnets This web site is devoted to magnetism and the cool experiments you can do with permanent magnets and electro-magnets. Some of the experiments are very basic - things you've done since second grade. Others are unique; perhaps you hadn't thought of doing some of these before, or had difficulty in trying to set them up. Lists of the materials needed for the demonstrations, directions on how to assemble them, instructions on how to show them, and notes on how they work are all here for you. Also shown are several cool magnetic toys you can buy. Of course, there are also links to useful sites, sources and books on magnets. Have fun experimenting! Rick Hoadley

Jump to: Project Description Personnel Project Description Magnetic levitation haptic devices allow users to interact with computed environments by manipulating a handle that is levitated by magnetic means. Users can translate and rotate the handle while feeling forces and torques from the virtual environment. The motors, encoders, linkages, gears, belts, cables, and bearings of traditional haptic devices are simply dispensed with in favor of a direct electrodynamic connection to the handle held by the user. The Microdynamic Systems Laboratory is working to provide low-cost high fidelity magnetic levitation haptic interfaces to additional researchers under an NSF Major Research Equipment grant by re-engineering our old magnetic levitation system to provide much higher performance while drastically reducing its cost. We are currently building a batch of 9 new systems for distribution to members of the magnetic levitation haptic consortium. The picture above illustrates the new systems. The purpose of the consortium is to foster greater utilization of this technology, to share research experiences and results, to develop and share haptic rendering software using the magnetic levitation haptic devices, and to work together as a community to apply the developed knowledge to important problems.

45. LANL: Superconductivity Technology Center: Magnetic Levitation Train
    Superconductivity Technology Center magnetic levitation trains The idea of MAGLEV transportation has been around since the early 1900s.

    Extractions: Japanese Maglev Train MLX01 on Test Bed Magnetically levitated (MAGLEV) trains are considered as a future application of HTS development. To understand why, we must look briefly at the history of the railroads. The development of trains and rails began in the early 1800s. The modern conventional train is no faster (~110 mph) than those of the late 1890s. So conventional trains have reached the end phase of their development. France, Germany, and Japan have developed "high-speed" or "bullet" trains capable of speeds of 150-180 mph. This improvement in speed is based upon improved rails and controls. However, this technology has also reached the end phase of its development. One limiting factor for these trains is the expensive and time-consuming maintenance of the rails. So it is the mechanical friction between train wheels and metal tracks that limit this technology. This leads us to the development of the magnetically levitated (no friction) trains. We briefly describe the history of this development. The idea of MAGLEV transportation has been around since the early 1900s. The benefit of eliminating the wheel/rail friction to obtain higher speeds and lower maintenance costs has great appeal. The basic idea of a MAGLEV train is to levitate it with magnetic fields so there is no physical contact between the train and the rails (guideways).

Magnetic levitation train technology can be used for urban travel at relatively low speeds (less than 100 km/h, or less than 62 mph). 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). Two different approaches to magnetic levitation train systems have been developed. The first, called

    Extractions: Share Blog Cite Print Email Bookmark ScienceDaily (Feb. 12, 1999) See also: The device is unique because it enables people to not only touch these objects, but to reach in and manipulate them in three dimensions as well. The new system also eliminates the bulky links, cables and mechanisms of current haptic interfaces in favor of a single, lightweight moving part, which floats on magnetic fields. The system has a bowl-shaped floating element containing six levitation coils surrounded by strong, permanent magnets. A protruding handle attached to the bowl is grasped by the computer user, enabling interaction with solid, three-dimensional models graphically depicted on the computer screen. The system is housed in a desktop-high cabinet. It has taken Hollis and his Ph.D. student, Peter Berkelman, five years to develop the haptic interface. They believe that future applications of the technology will be in computer-augmented design, medical training, entertainment, flight simulation and the interactive control of remote robots. http://www.cs.cmu.edu/~msl

    Extractions: E CP's unique MagLev apparatus dramatically demonstrates closed loop levitation of permanent and ferromagnetic elements. The apparatus includes laser feedback and high flux magnetics to affect large displacements and provide visually stimulating tracking and regulation demonstrations. The system is quickly set up in the open loop stable and unstable (repulsive and attractive fields) configurations shown. By adding a second magnet, two SIMO plants may be created, and by driving both actuators with both magnets, MIMO control is studied. The inherent magnetic field nonlinearities may be inverted via provided real-time algorithms for linear control study or the full system dynamics may be examined. Disturbances may be introduced via the second drive coil for demonstrating system regulation in SISO and SIMO operation The field interaction between the two magnets causes strong cross coupling and thus produces a true multi-variable system. The inherent magnetic field nonlinearities may be inverted via provided real-time algorithms for linear control implementation or the full system dynamics may be studied. This plant provides substantially more configuration flexibility and, by virtue of its dramatically greater levitation travel range, greater visual impact in demonstrations than any other educational maglev system.

WorldHeart The Levacor pushes blood from the heart into the circulatory system. WorldHeart Back in 1982, Barney Clark, a 61-year-old dentist, was implanted with the world's first artificial heart, the Jarvik-7, a cumbersome piece of equipment with complicated external mechanisms. The device, which extended Clark's life for 112 days, required the patient to be hooked up, via hose-like tubes emerging from his chest, to a machine the size of a laundry dryer. The machine supplied bursts of air that helped to pump the mechanical heart. Today's medical-device designers foresee a more independent existence for patients suffering from heart failure. Just as the designers of popular consumer electronics such as Apple's ( AAPL ) iPod or Motorola's ( MOT ) RAZR phone have been able to slim their products to wafer-thinness, medical engineers and consultants are employing similar strategies and innovations to create slimline devices that are genuinely life-enhancing.

Chiang (first draft 8/7/2004) Simple and inexpensive levitation no batteries, no liquid nitrogen, and no complicated electronic circuits. Stable passive diamagnetic levitation at room temperature using permanent magnets Many people have seen levitation tricks. A common one is a magnet floating above a piece of YBCO high-temperature superconductor cooled by liquid nitrogen. One can also levitate a frog (or other animals or objects) with a very powerful superconducting magnet. But these tricks are hard to do at home. For levitation enthusiasts, here is a simple experiment. You can levitate a piece of graphite at room temperature using powerful permanent magnets. The cost can be as low as a dollar. Pictures for a quadrupole set. These are some of the simplest configurations. The magnets are arranged with the north poles of adjoining magnets alternately pointing up and down. The magnets are neodymium-iron-boron (NIB) magnets coated with nickel or gold. Small ones are inexpensive. You can find many vendors on the web. You can also find such magnets in some stores. NIB magnets of 0.5-inch size or larger can be dangerously powerful and should not be used by beginners. Keep the magnets away from medical equipment, computers, monitors, TVs, cards with magnetic strips, and other magnetic objects. You can use fairly small ones for levitation. The 3x3 configuration above uses 1/8-inch cubes. High grade NIB magnets (N50 for example) are better, but the cost is higher. N38 grade is more common and cheaper, and works nearly as well.

The core is a super conducting material which conducts electric current without any resistance at temperatures below minus 180 degrees Celsius (minus 292 degrees Fahrenheit). In this state it can trap magnetic fields. The resulting magnetic forces cause not only the levitation but precision control above the rail, which is made of conventional magnetic material.
