    Extractions: MSL Projects Magnetic Levitation Haptic Interfaces - Early Work Peter Berkelman, Zack Butler, and Ralph Hollis This project advances knowledge about how to give computer users convincingly real haptic (sense of touch) interaction with computers. While there has been some progress in this area, chiefly through the use of back-driven robotic-like manipulators, this is a substantially new approach which promises a qualitative leap in improvement of such capabilities: A user interacts with the computer by grasping a rigid tool whose behavioral description is computed, employing this tool to interact with computed environments which are semantically meaningful in terms of the application. At the same time, the environment exerts realistic forces and torques on the tool's handle which are felt by the user. The vision is one of providing the computer user immediate, high-fidelity, convincingly real interaction with computed environments. The new haptic interface approach is based on a recently developed magnetic levitation technology, and on recent strong advances in the art of physically-based simulation. The magnetic levitation technology uses Lorentz forces to stably levitate and control a rigid body (which includes the handle through which the user interacts) in six degrees of freedom, giving a new and heretofore unexplored physical basis for haptic interaction.

    Extractions: 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).

44. Superconducting Levitation
    Measurements on a Superconductor @ UBC Physics and Astronomy Outreach Other levitationmovies @ HyperPhysics Experiments with magnetic levitation by Rick  
    http://www.fys.uio.no/super/levitation/
    
    Extractions: 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. 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.

    http://math.ucr.edu/home/baez/physics/General/Levitation/levitation.html
    
    Extractions: Original by Philip Gibbs and Andre Geim, March 1997. A theorem due to Earnshaw proves that it is not possible to achieve static levitation using any combination of fixed magnets and electric charges. Static levitation means stable suspension of an object against gravity. There are, however, a few ways to levitate by getting round the assumptions of the theorem. In case you are wondering, none of these can be used to generate anti-gravity or to fly a craft without wings or jets. The proof of Earnshaw's theorem is very simple if you understand some basic vector calculus. The static force as a function of position F x acting on any body in vacuum due to gravitation, electrostatic and magnetostatic fields will always be divergenceless. div F . At a point of equilibrium the force is zero. If the equilibrium is stable the force must point in towards the point of equilibrium on some small sphere around the point. However, by Gauss' theorem, F x ).d

    Extractions: 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.

    Extractions: Colorado Department of Transportation - Magnetic Levitation Research PUBLIC INFORMATION PACKAGE The Colorado Department of Transportation has entered into a "Memorandum of Understanding" to conduct research and development under the federal Urban Magnetic Levitation program. The other parties to this agreement are: Colorado Intermountain Fixed Guideway Authority (CIFGA) Sandia National Laboratories (SNL) MagLev Transit Group (MTG) In 1999, CIFGA and SNL were identified by the US Congress to each receive $1.75M to study and develop magnetic levitation technology for use in urban transit. MTG was selected, based on competitive proposals, by the Federal Transit Administration (FTA) to receive $742,000 to conduct magnetic levitation research. CDOT is receiving these $4,242,000 in grant funds through a cooperative agreement with the FTA and is contracting with the three participants to conduct the research and development. The state funds being used for appropriately related analysis in the ongoing I-70 west Programmatic Environmental Impact Study (I-70 PEIS) provide the required match. The I-70 PEIS study is expected to be result in a Record of Decision in 2004. CDOT is working in partnership with the other groups involved to provide accurate and complete information regarding possible advanced technology alternatives for the I-70 West Corridor. Information about this system, along with information on other fixed guideway systems, and highway, rubber-tire transit (bus), and other transportation alternatives, will be used to determine a preferred alternative for a long-term plan for the corridor.

    Extractions: Using Piezoelectric Actuator Keywords: Magnetic Levitation, Piezoelectric Actuator, Permanent Magnet Abstract A type of magnetic levitation system with permanent magnet motion control has been already proposed. The feature is to control attractive force of permanent magnet using actuator. Based on this principle, a 1 DOF hanging type magnetic levitation system has been developed. The levitated object hangs from the upper ferromagnetic ceiling. This system had problem that the levitated object swings. Next step is development of a 3 DOF magnetic levitation system. A 3 DOF magnetic levitation system that can control the DOFs of the rotation about horizontal axes is developed. This paper describes the success of a 3 DOF magnetic levitation system using permanent magnets and piezoelectric actuators. INTRODUCTION The need for a very clean environment is increasing in such areas as semiconductor processing and biotechnological experiments. During conveyance and handling of an object, dust and particles are generated from contact points. The conveyance vehicles used in these areas must eliminate contamination. Thus mechanical contacts are the prime origins of dust and particle generation. A non-contact conveyance mechanism is good solution for clean environment applications. Most of magnetic levitation system is a type of system which controls attractive force of electromagnet by varying electric current. Also, a type of magnetic levitation system which controls attractive force of permanent magnet by varying air gap length has been already proposed

    Extractions: Fill out our online form Email Us Report a dead link Magnetic Levitation (MAGLEV) Magnetic levitation or Maglev refers to a super speed train levitated above a guideway by magnets. Using electricity, the magnets also propel the train on a cushion of air at speeds up to 300 miles per hour. Recently Congress approved TEA 21 - the largest transportation bill in history - that included $1.1 billion for Maglev deployment. Of the $1.1 billion for Maglev, the first $60 million has been spent on studies of the technology in seven corridors nationally. Based on the results of the studies, the US Department of Transportation will select one project to receive $950 million in federal construction funds. The Maglev Maryland project has moved into high gear. Phyllis Wilkins, Executive Director of Maglev Maryland for Baltimore Development Corporation (BDC), has been coordinating the regional effort since its inception working with the Departments of Transportation for Maryland and Washington, DC. Maryland Mass Transit Administration (MTA) is managing the study being conducted by a consulting team. In 1992, Maryland received a grant to perform the first Maglev feasibility study through the ISTEA transportation bill. The feasibility study released in 1994 has been widely recognized as one of the finest in the country and is the foundation for the current study efforts.

    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.
