Extractions: Magnetic Levitation Technologies The conventional method to determine the output power of a laser to a high precision involves a large apparatus and requires a substantial effort. Using magnetic levitation to create a suspension free sensor for the output power of a laser beam will allow us to offer a desktop size apparatus with similar performance. A magnetic disk, suspended in a magnetic field by several larger magnets, is outfitted with two signal reflectors, one on each side. Each side reflects an incoming laser beam. One of the laser beams is object of the output study and the other beam comes from a laser displacement measurement instrument which records the relative displacement of the magnetic disk due to the impact of the first laser beam. Modulating the laser beam that is being measured results in a harmonic oscillation of the magnetic and from this oscillation we calculate the output power of the laser.

http://van.hep.uiuc.edu/van/qa/section/Electricity_and_Magnets/Maglev/2002040109

Extractions: caracas venezuela 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.

http://van.hep.uiuc.edu/van/qa/section/Electricity_and_Magnets/Maglev/2001040911

Extractions: Yes, the magnet can float another magnet directly above it. However, this is not a stable position. The magnet you have above it will want to flip upsidedown so that it is attracted to the lower magnet. The magnet in the middle would also have a tendancy to move to the side to get away from the field. If you were to fix the position of the magnets so they don't drift or rotate, then you could get some small shock suppression, but the force you get is very small when compared to a spring. So this is not very efficient.

CRYOCOOLERS II.4.F. Magnetic Levitation The new Japanese Maglev test line started operation in spring 1997. Meanwhile, more than 10 000 km testing experience has been gathered on the 18.4 km long Yamanashi track, where 80 % of the way is leading through tunnels [1, 2]. Two trains with three cars each have been completed. The designed maximum speed of 550 km/h planned for a future commercial use connecting Osaka and Tokyo within an one hour drive, was achieved by the end of 1997 [3]. In a collaboration with ISTEC, the use of melt-textured YBCO samples as a direct substitute of the NbTi coils is investigated [11]. The superconducting and the mechanical properties of state-of-the-art YBCO pellets proved to be not sufficient yet for a reproduction of the fields generated by the NbTi coils. As for the screening of the magnetic fields of the coils from the passenger rooms, the size and the cost of melt-textured YBCO do not yet fit the practical needs [11].

Extractions: Education An interview with Peter Berkelman and Ralph Hollis, Robotics Institute, Carnegie Mellon University. Please define haptic. Berkelman: Haptic means interacting through a sense of touch that combines tactile and kinesthetic sensations. Haptic interaction is a relatively new research field. Several research groups are developing various kinds of devices, including linkage devices, tension cable devices, or exoskeletons that all try to give the user the sensation or experience of physically interacting with some kind of virtual or remote environment. The other wording is magnetic levitation. How does that work? You have a stator and flotor?

Extractions: March 11, 2002 NASA's new maglev track NASA has a new magnetic levitation track. It is at Marshall Space Flight Center in Huntsville, Alabama. Engineers will be using the track to experiment with magnetic levitation, called maglev. Maglev uses magnets to lift a vehicle and then move it forward very quickly. Engineers think that maglev could be used to give rockets a running start. The maglev would get the rocket going very fast on a track, then the rocket would start its engines and take off. This would use a lot less rocket fuel, and would be much cheaper. NASA's 50' outdoor track The new track is 44 feet long. It can

Extractions: Leaving science fiction aside, science does know scores of different ways to levitate things. For instance, a helicopter can be considered as a very impressive levitation device that uses a stream of air to keep floating. Scientists have also found many ways to levitate things without any noise or the need for petrol or air, by using electromagnetic fields. Levitating trains and levitating displays are but two examples of electromagnetic levitation. However, in all such schemes, a source of energy (an engine or a battery at least) is always required to keep an object afloat. Remove the battery and the levitation inevitably stops Today's science knows only one way to achieve REAL levitation, i.e. such that no energy input is required and the levitation can last forever. The real levitation makes use of diamagnetism , an intrinsic property of many materials referring to their ability to expel a portion, even if a minute one, of an external magnetic field. Electrons in such materials rearrange their orbits slightly so that they expel the external field. As a result, diamagnetic materials repel and are repelled by strong magnetic fields. SUPERCONDUCTING LEVITATION Superconductors are ideal diamagnetics and completely expel magnetic field at low temperatures. The picture shows a sumo wrestler standing on a levitating magnet platform that floats above a high-temperature superconductor. The superconductor is cooled by liquid air and hidden below the platform. To learn more about superconducting levitation, click on the title above (this is not our work) or search the web.

http://www.ecpsystems.com/controls_maglevit.htm

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.
