This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor. The servo controls keep it safely at a constant distance from the track. As the viscosity of the liquid changes, it offers a difference in the damping. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below.

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. However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. The effect can be used for stunts such as levitating a telephone book by concealing an aluminium plate within it.

The net effect is to more than triple the lift force. 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. To calculate the amount of lift, a magnetic pressure can be defined. Using two opposed Halbach arrays increases the field even further. 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. Litz wire made of wire thinner than the skin depth for the frequencies seen by the metal works much more efficiently than solid conductors. Either system represents examples of ElectroMagnetic Suspension (EMS). The effect can be used for stunts such as levitating a telephone book by concealing an aluminium plate within it.

Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable. Magnetic fields are conservative forces and therefore in principle have no built-in damping, and in practice many of the levitation schemes are under-damped and in some cases negatively damped.

Although this type of suspension offers a very comfortable ride, sport settings can be applied or tuned into the system to cater for performance vehicles.

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. Magnetic ride control uses a system known as magneto rheological technology for suspension damping. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. 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.

The two primary issues involved in magnetic levitation are lifting forces : providing an upward force sufficient to counteract gravity, and stability : ensuring that the system does not spontaneously slide or flip into a configuration where the lift is. 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. 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.

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. 5 This can permit vibration modes to exist that can cause the item to leave the stable region.

An explanation of magnetic suspension also referred to as magnetic ride control and it's benefits when used on high end vehicles. The effect can be used for stunts such as levitating a telephone book by concealing an aluminium plate within it. As the viscosity of the liquid changes, it offers a difference in the damping. 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.

Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to. 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.

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