Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. 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. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. Magnetic ride control uses a system known as magneto rheological technology for suspension damping.

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. 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.

For example, the magnetic pressure of a magnetic field on a superconductor can be calculated by: where is the force per unit area in pascals, is the magnetic field just above the superconductor in teslas, and 4107 NA2 is the permeability. For the form of transportation, see. Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes.
Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below. EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below. 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.
Dynamic stability edit Dynamic stability occurs when the levitation system is able to damp out any vibration-like motion that may occur. 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 viscosity of the polymer liquid can be changed to an almost solid state similar to plastic or rubber in composition. 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. To calculate the amount of lift, a magnetic pressure can be defined. An explanation of magnetic suspension also referred to as magnetic ride control and it's benefits when used on high end vehicles. 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. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. For the form of transportation, see. Magnetic suspension or magnetic ride control is used by a range of Cadillac vehicles and several other high end vehicles from General Motors (GM) like the Chevrolet Corvette.

For example, the magnetic pressure of a magnetic field on a superconductor can be calculated by: where is the force per unit area in pascals, is the magnetic field just above the superconductor in teslas, and 4107 NA2 is the permeability. 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. 6 Halbach arrays are also well-suited to magnetic levitation and stabilisation of gyroscopes and electric motor and generator spindles. As the viscosity of the liquid changes, it offers a difference in the damping. 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. ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. 5 This can permit vibration modes to exist that can cause the item to leave the stable region.
As the viscosity of the liquid changes, it offers a difference in the damping. Ferrari uses them in most of their vehicles and Audi uses them in the TT and their supercar, the R8.

The primary ones used in maglev trains are servo-stabilized electromagnetic suspension (EMS electrodynamic suspension (EDS). Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable. 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?
