Magnetic levitation From Wikipedia, the free encyclopedia. Magnetic levitation is the process by which an object is suspended above another object with no other support but magnetic fields. The electromagnetic force is used to counteract the effects of the gravitational force Earnshaw's theorem proved conclusively that it is not possible to levitate using static, macroscopic, "classical" electromagnetic fields. The forces acting on an object in any combination of gravitational, electrostatic, and magnetostatic fields will make the object's position unstable. However, several possibilities exist to make levitation viable, by violating the assumptions of the theorem.

Earnshaw's theorem does not apply to diamagnets since they behave in the opposite manner of a typical magnet (relative permeability r paramagnetic or ferromagnetic properties. A material which is predominantly diamagnetic will be repelled by a magnet, although typical objects only feel a very small force. This can be used to levitate light pieces of

A magnetic levitation train or maglev is a train -like vehicle that is suspended in the air above the track, and propelled forward using the repulsive and attractive forces of magnetism . Because of the lack of physical contact between the track and the vehicle, the only friction is that between the carriages and the air. Consequently maglev trains can travel at very high speeds with reasonable energy consumption and noise levels (systems have been proposed that operate at up to 650 km/h, which is far faster than is practical with conventional rail transport ). Whilst the very high maximum speeds make maglev trains potential competitors to airliners on many routes, the enormous cost of constructing the tracks has limited maglev vehicles largely to demonstration projects. Technology There are two primary types of maglev technology: One that relies on superconducting magnets and a newer, potentially more economical system that uses permanent magnets.

75. The Actinide Research Quarterly: 3rd Quarter 1998 Magnetic Levitation Results in HighPurity Plutonium Metal. Plutonium, a member of the actinide series of elements, exhibits seven unique crystal structures http://lanl.gov/orgs/nmt/nmtdo/AQarchive/98fall/magnetic_levitation.html

contents Magnetic Levitation Results in High-Purity Plutonium Metal Figure 1 . Levitation zone refining apparatus illustrated with a stainless steel rod loaded in the cold boat. The hot zone on the rod can be clearly seen from the red glow caused by the induction from the coil. A comprehensive knowledge is lacking for plutonium, compared to the level of knowledge for other elemental metals. The high degree of complexity in plutonium's intrinsic properties severely restricts extrapolation of knowledge from surrogate metallic systems. Consequently, fundamental measurements on well-characterized, research-grade (100 to 200 ppm total impurities) plutonium are required. Therefore, our efforts are directed at the preparation and characterization of large quantities (200 to 300 g) of research-grade plutonium, in support of fundamental experimentation. Figure 2. Molten plutonium metal in a levitated state in the middle of the crucible. Enough gallium has been added to stabilize the delta phase upon solidification (see Figure 3). Our approach to the preparation of research-grade plutonium metal is to start with doubly electrorefined, vacuum-cast plutonium metal and further purify it using levitation zone refining in concert with levitation distillation at reduced pressure. In particular, levitation zone refining targets metals and metalloids while levitation vacuum distillation targets decay products and gases. Double-electrorefined plutonium that has been chill-cast contains 500 to 600 ppm total impurities. Impurity totals are derived from mass spectrometry and atomic emission data in which 75 to 80 trace elements are analyzed for and then quantified. Historically, 20 to 40 elements represent the typical range of elements documented in the early literature.

The electromagnetic force is used to counteract the effects of the gravitational force Magnetic levitation transport, or maglev, is a form of transportation that suspends, guides and propels vehicles ( especially trains ) via electromagnetic force. This method can be faster than wheeled mass transit systems, potentially reaching velocities comparable to turboprop and jet aircraft ( 900km/h, 559 mph ). The maximum recorded speed of a maglev train is 581km/h ( 361 mph ), achieved in Japan in 2003.
