The electromagnet is above the object being levitated; the electromagnet is turned off whenever the object gets too close, and turned back on when it falls further away.

Delphi Automotive ha sido la encargada de desarrollar la primera aplicacin industrial de un fluido cuya viscosidad vara ante la presencia de un campo. 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. 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 Cadillac CTS-V uses magnetic suspension/magnetic ride control and has earned the respect of many for its ride comfort/handling compromise as much as its powerful engine. 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.
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. Stable magnetic levitation can be achieved by measuring the position and speed of the object being levitated, and using a feedback loop which continuously adjusts one or more electromagnets to correct the object's motion, thus forming a servomechanism. ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. 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.
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.

Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below.

Using two opposed Halbach arrays increases the field even further. 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. 1 Essentially all types of magnets have been used to generate lift for magnetic levitation; permanent magnets, electromagnets, ferromagnetism, diamagnetism, superconducting magnets and magnetism due to induced currents in conductors. 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. 6 Halbach arrays are also well-suited to magnetic levitation and stabilisation of gyroscopes and electric motor and generator spindles. 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.
Stable magnetic levitation can be achieved by measuring the position and speed of the object being levitated, and using a feedback loop which continuously adjusts one or more electromagnets to correct the object's motion, thus forming a servomechanism. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. 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? Magnetic ride control uses a system known as magneto rheological technology for suspension damping. Contents A superconductor levitating a permanent magnet. Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law. 5 This can permit vibration modes to exist that can cause the item to leave the stable region. Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. 1 Essentially all types of magnets have been used to generate lift for magnetic levitation; permanent magnets, electromagnets, ferromagnetism, diamagnetism, superconducting magnets and magnetism due to induced currents in conductors.
Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Again, litz wire gives the best results.
