    Extractions: In a message dated 10/14/02 08:29:13 PM, Adgrossman@livecapital.com writes: Jerry began by explaining that Magna Force was founded in 1993 to "develop from prototype to production disruptive, bold and visionary permanent magnet technologies for licensing." It is a private Washington State Corporation that holds 18 U.S. Patents and more than 200 worldwide patents. The companies newest project is LevX technology, which is "the development of apparatuses, systems and methods for levitating and moving objects." He then shared a couple of his companies big success stories, magnetic couplings for mechanical power distribution. Lamb explained that companies that have installed them have saved a lot of energy. Then he talked a bit about what the LevX system is. It consists of rails very much like the ones under trains now, except that the surface is tiled with permanent magnets an inch or two thick with all of the poles pointing the same direction. The cars that glide on the rails have permanent magnets arranged over the tracks so that the poles are oriented to repel the track's magnets. Because the magnets are so strong, an inch or so of air gap is as close as the track and cars come. Since the vehicle is riding on air, there is no friction loss, making very energy efficient transportation possible. Lamb then showed us pictures of Washington State Republican Legislators riding his prototype train. He listed for us some of the many possible applications for the technology, things such as people movers, materials handling for assembly lines, military launching catapults, or even heavy freight shipping. He shared some mouth watering price points, things like building rail lines for only $2 million per mile. He then completed the excitement building by showing us a half hour video of news clippings the LevX system had gotten, including footage of Washington State Governor Locke standing in front of a Corvette floating on a LevX track saying that LevX has great potential.

If the tests are done, approved, and construction begins on time, Beijing will be the first city in China to have a high-tech railway by 2002, the 2.6-kilometre-long maglev will be built in the Badaling Section of the Great Wall in northwestern suburban Beijing. Shanghai is looking at building a 35-kilometre-long maglev route to run through downtown Shanghai that is believed to play a big role in the city’s transportation system.

    http://www.sri.com/news/releases/05-30-00.html
    
    Extractions: MENLO PARK, Calif. (May 23, 2000) - Silicon Valley-based SRI International received both "Best of Show" awards at the Sensors and Motion Control Expositions (May 9 to 11, 2000) for its passive diamagnetic levitation system. SRI's entry won against dozens of other entries for top honors at the events, reaffirming the organization's role as a leading technology innovator. The passive diamagnetic levitation system makes non-contact suspension and transportation possible without the use of electromagnets, control systems or power. The Sensors and Motion Control Expositions are the only events dedicated to the utilization of sensor and motion technologies and their related applications. This year's expositions, held concurrently at the Anaheim Convention Center in Anaheim, California, and sponsored by Sensors Magazine and the American Institute of Motion Engineers respectively, brought together over 325 companies displaying a full range of related technologies. Diamagnetism is a property of some materials such as graphite that causes them to levitate in a stable manner in a magnetic field without power. SRI has studied this phenomenon and has recently developed passive diamagnetic levitation system technologies for several useful devices. Passive diamagnetic levitation system technology has a broad range of applications, from precise seismic sensors to frictionless micromotors, and is particularly valuable for use in clean room transport to eliminate particulate contaminants.

    Extractions: WASHINGTON Consider it a stretch of the imagination or the ultimate high-wire act. All aboard the space elevator, to be whisked above Earth in an electromagnetic-powered cable car. Taking an elevator to space has largely been in the realm of science fiction more engineering fancy than fact. But recent studies suggest that a melding of space tether, magnetic levitation and carbon nanotube technologies could transform this "Jack and the Beanstalk" idea into a mass transit system for the 21st century space traveler. Uptown traffic Keep your mind open and think big. The space elevator concept is based on a structure stretching from the Earth's surface, up through the atmosphere, all the way to geostationary Earth orbit 22,300 miles (36,000 kilometers) high above the equator.

    Extractions: pp. 2176-2194 Abstract. In this paper we present an analysis of a new configuration for achieving spin stabilized magnetic levitation. In the classical configuration, the rotor spins about a vertical axis; the spin stabilizes the lateral instability of the top in the magnetic field. In this new configuration the rotor spins about a horizontal axis; the spin stabilizes the axial instability of the top in the magnetic field. Key words.

    Plenty of materials can be levitated in a strong magnetic field from simple metals, liquids, and various polymers to everyday things such as various plants and living creatures (frogs, fish and a mouse).

    Extractions: Whether an object will or will not levitate in a magnetic field B is defined by the balance between the magnetic force F = M B and gravity mg = V g where is the material density, V is the volume and g = 9.8m/s . The magnetic moment M = ( )VB so that F = ( )BV B = ( )V B . Therefore, the vertical field gradient B required for levitation has to be larger than g/ . Molecular susceptibilities are typically for diamagnetics and for paramagnetic materials and, since is most often a few g/cm , their magnetic levitation requires field gradients and 10 T /m, respectively. Taking l = 10cm as a typical size of high-field magnets and B ~ B /l as an estimate, we find that fields of the order of 1 and 10T are sufficient to cause levitation of para- and diamagnetics. This result should not come as a surprise because, as we know, magnetic fields of less than 0.1T can levitate a superconductor ( = -1) and, from the formulas above, the magnetic force increases as

     Extractions: Click on image for larger view There are some materials that are more diamagnetic than bismuth. These include superconductors (which at this time require cryogenic temperatures to work), and similar materials that exhibit "giant diamagnetism" (also at very low temperatures). But there is one material that is more diamagnetic than bismuth at room temperature, at least in one direction. That material is called pyrolytic graphite Pyrolytic graphite is a synthetic material, made by a process called chemical vapor deposition To make pyrolytic graphite, methane gas at low pressure (about 1 Torr) is heated to 2000 degrees Celsius. Very slowly, (one thousandth of an inch per hour) a layer of graphite grows. The graphite made this way is very highly ordered, and the layers of carbon atoms form like a crystal of hexagonal sheets. These sheets lie on top of one another like sheets of mica. You can separate the layers with a sharp knife to make thinner sheets. Click on image for larger view Pyrolytic graphite is more diamagnetic than bismuth, but only in the direction perpendicular to the sheets of carbon. In other directions, it is still diamagnetic, but not as good as bismuth.
