Magnetic suspension can adapt to uneven road surfaces several hundred times per second, in fact it takes only a few milliseconds to adjust any one of the shock absorbers. Delphi Automotive ha sido la encargada de desarrollar la primera aplicacin industrial de un fluido cuya viscosidad vara ante la presencia de un campo. 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.

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. 5 This can permit vibration modes to exist that can cause the item to leave the stable region. Induced currents edit Main article: electrodynamic suspension These schemes work due to repulsion due to Lenz's law. 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. 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.

Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below. These kinds of systems typically show an inherent stability, although extra damping is sometimes required. 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.

At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. Either system represents examples of ElectroMagnetic Suspension (EMS). 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. 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 can adapt to uneven road surfaces several hundred times per second, in fact it takes only a few milliseconds to adjust any one of the shock absorbers.

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. This ensures a comfortable ride along various road surfaces. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it.

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. 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.

Many systems use magnetic attraction pulling upwards against gravity for these kinds of systems as this gives some inherent lateral stability, but some use a combination of magnetic attraction and magnetic repulsion to push upwards. 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. 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. 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. 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. 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. Contents A superconductor levitating a permanent magnet. 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. 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.

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. Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. 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. Magnetic materials and systems are able to attract or press each other apart or together with a force dependent on the magnetic field and the area of the magnets, For example, the simplest example of lift would be a simple.
