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. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. MagneRide is an automotive adaptive suspension with Magnetorheological damper system developed by the Delphi Automotive corporation 1 2 and now owned by Beijing. 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. 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. 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. As the viscosity of the liquid changes, it offers a difference in the damping. Each absorber is filled with a polymer liquid containing many small magnetic particles.

Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. The reduction of body roll may reduce the need for anti roll bars. 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. 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. To calculate the amount of lift, a magnetic pressure can be defined.

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. 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. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load.

At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal.

Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.

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. Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below.

Each absorber is filled with a polymer liquid containing many small magnetic particles. With a multitude of new products waiting to be released, including several cars, I thought this might be a good time to revisit an old friend for. The effect can be used for stunts such as levitating a telephone book by concealing an aluminium plate within it. 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 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.

This article is about the physical phenomenon. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. Again, litz wire gives the best results. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea.

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. Either system represents examples of ElectroMagnetic Suspension (EMS). This ensures a comfortable ride along various road surfaces. Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below. Dynamic stability edit Dynamic stability occurs when the levitation system is able to damp out any vibration-like motion that may occur. 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. 9 One source of oscillating magnetic field. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal.
