When a conductor is presented with a time-varying magnetic field electrical currents in the conductor are set up which create a magnetic field that causes a repulsive effect. The net effect is to more than triple the lift force. 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. 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. 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. Contents A superconductor levitating a permanent magnet. This ensures a comfortable ride along various road surfaces. As the viscosity of the liquid changes, it offers a difference in the damping.

Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable. 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.

However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. 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. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.

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.

Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. 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 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.

Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. The reduction of body roll may reduce the need for anti roll bars. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. When a conductor is presented with a time-varying magnetic field electrical currents in the conductor are set up which create a magnetic field that causes a repulsive effect. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law. Eddy current damping (conductive metal influenced by field) tuned mass dampers in the levitated object electromagnets controlled by electronics Methods edit Mechanical constraint (in this case the lateral restrictions created by a box) can permit pseudo-levitation of permanent magnets For.

The primary ones used in maglev trains are servo-stabilized electromagnetic suspension (EMS electrodynamic suspension (EDS). EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below.

Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes. 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. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. 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.

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 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. 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. 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. This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor.
