Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. Ferrari uses them in most of their vehicles and Audi uses them in the TT and their supercar, the R8. An especially technologically interesting case of this comes when one uses a Halbach array instead of a single pole permanent magnet, as this almost doubles the field strength, which in turn almost doubles the strength of the eddy currents. 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? Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable.

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. This effect requires non-ferromagnetic but highly conductive materials like aluminium or copper, as the ferromagnetic ones are also strongly attracted to the electromagnet (although at high frequencies the field can still be expelled) and tend to have a higher resistivity. Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields.
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 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. 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.

This effect requires non-ferromagnetic but highly conductive materials like aluminium or copper, as the ferromagnetic ones are also strongly attracted to the electromagnet (although at high frequencies the field can still be expelled) and tend to have a higher resistivity. 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.
However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. 5 This can permit vibration modes to exist that can cause the item to leave the stable region.
MagneRide - Wikipedia, the free encyclopedia
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. Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes. This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor. The viscosity of the polymer liquid can be changed to an almost solid state similar to plastic or rubber in composition. Each absorber is filled with a polymer liquid containing many small magnetic particles. Either system represents examples of ElectroMagnetic Suspension (EMS). These kinds of systems typically show an inherent stability, although extra damping is sometimes required. To calculate the amount of lift, a magnetic pressure can be defined. As the viscosity of the liquid changes, it offers a difference in the damping.
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.

Autos de Colecciуn. 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. 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.

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. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load.
Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. 7 8 Since the eddy currents create their own fields which oppose the magnetic field, the conductive object is repelled from the electromagnet, and most of the field lines of the magnetic field will no longer penetrate the conductive object.
