Relative motion between conductors and magnets edit If one moves a base made of a very good electrical conductor such as copper, aluminium or silver close to a magnet, an ( eddy ) current will be induced in the conductor. The viscosity of the polymer liquid can be changed to an almost solid state similar to plastic or rubber in composition. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. For a very simple example, some tabletop levitation demonstrations use this principle, and the object cuts a beam of light to measure the position of the object. Although this type of suspension offers a very comfortable ride, sport settings can be applied or tuned into the system to cater for performance vehicles. 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.
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. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. Either system represents examples of ElectroMagnetic Suspension (EMS). Ikea Billy bookcases with beadboard back, baseboard crown molding and batten trim on endpieces Our House: Room by Room. Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below. The servo controls keep it safely at a constant distance from the track.
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. 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. Magnetic Suspension or magnetic ride control is a type of suspension system where the shock absorbers reacts to the road and adjusts much faster than regular absorbers.

Delphi Automotive ha sido la encargada de desarrollar la primera aplicacin industrial de un fluido cuya viscosidad vara ante la presencia de un campo magntico y lo ha denominado MagneRide.
Earnshaw's theorem proved conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields. 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.

However, several possibilities exist to make levitation viable, for example, the use of electronic stabilization or diamagnetic materials (since relative magnetic permeability is less than one 4 it can be shown that diamagnetic materials are stable along at least one. 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.
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. Magnetic materials and systems are able to attract or press each other apart or together with a force dependent on the magnetic field and the area of the magnets, For example, the simplest example of lift would be a simple. Earnshaw's theorem proved conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields. 5 This can permit vibration modes to exist that can cause the item to leave the stable region. ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. MagneRide is an automotive adaptive suspension with Magnetorheological damper system developed by the Delphi Automotive corporation 1 2 and now owned by Beijing. 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. Static stability edit Static stability means that any small displacement away from a stable equilibrium causes a net force to push it back to the equilibrium point.

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. 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. 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. 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. If two magnets are mechanically constrained along a single axis, for example, and arranged to repel each other strongly, this will act to levitate one of the magnets above the other. Each absorber is filled with a polymer liquid containing many small magnetic particles. Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.
