Ferrari uses them in most of their vehicles and Audi uses them in the TT and their supercar, the R8. At high frequencies (a few tens of kilohertz or so) and kilowatt powers small quantities of metals can be levitated and melted using levitation melting without the risk of the metal being contaminated by the crucible. The viscosity of the polymer liquid can be changed to an almost solid state similar to plastic or rubber in composition. Magnetic ride control uses a system known as magneto rheological technology for suspension damping. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. From Earnshaw's theorem at least one stable axis must be present for the system to levitate successfully, but the other axes can be stabilized using ferromagnetism. The two primary issues involved in magnetic levitation are lifting forces : providing an upward force sufficient to counteract gravity, and stability : ensuring that the system does not spontaneously slide or flip into a configuration where the lift is. ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. Using two opposed Halbach arrays increases the field even further.

In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. 3 For example, the simplest example of lift with two simple dipole magnets repelling is highly unstable, since the top magnet can slide sideways, or flip over, and it turns out that no configuration of magnets can produce stability. The reduction of body roll may reduce the need for anti roll bars. Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law.
The effect can be used for stunts such as levitating a telephone book by concealing an aluminium plate within it. Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. An electrical charge is sent to the liquid in the absorber which immediately changes the position of the particles in the liquid and its viscosity. Magnetic suspension can adapt to uneven road surfaces several hundred times per second, in fact it takes only a few milliseconds to adjust any one of the shock absorbers.

Magnetic ride control uses a system known as magneto rheological technology for suspension damping. Using two opposed Halbach arrays increases the field even further. Another benefit is that these dampers easily offers the best of both worlds in the ride comfort/handling compromise that many other suspension systems are subjected to.

Las hay de diferentes estilos y tamaos para satisfacer todo tipo de gustos y necesidades. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. 2 Stability edit Earnshaw's theorem proves that using only paramagnetic materials (such as ferromagnetic iron) it is impossible for a static system to stably levitate against gravity. MagneRide is an automotive adaptive suspension with Magnetorheological damper system developed by the Delphi Automotive corporation 1 2 and now owned by Beijing. 9 One source of oscillating magnetic field. The primary ones used in maglev trains are servo-stabilized electromagnetic suspension (EMS electrodynamic suspension (EDS). Magnetic dampers are designed with similar dimensions and connection points to other types of dampers so they are usually attached to the chassis of the vehicle similar to how a coil spring suspension would. Delphi Automotive ha sido la encargada de desarrollar la primera aplicacin industrial de un fluido cuya viscosidad vara ante la presencia de un campo. The forces acting on any paramagnetic object in any combinations of gravitational, electrostatic, and magnetostatic fields will make the object's position, at best, unstable along at least one axis, and it can be unstable equilibrium along all axes.
Whether the magnetic suspension is soft for comfort or firm for performance it maintains the quick reaction time to change the damping immediately when required?

Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. Servomechanisms edit The Transrapid system uses servomechanisms to pull the train up from underneath the track and maintains a constant gap while travelling at high speed Main article: Electromagnetic suspension The attraction from a fixed strength magnet decreases with increased. The net effect is to more than triple the lift force.
