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. 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. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc.

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. Each absorber is filled with a polymer liquid containing many small magnetic particles. 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. 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. 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. Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable.

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. Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. 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. 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.

However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. 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. 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. An explanation of magnetic suspension also referred to as magnetic ride control and it's benefits when used on high end vehicles.

5 This can permit vibration modes to exist that can cause the item to leave the stable region. 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. 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. This article is about the physical phenomenon.

At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below. 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. 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. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.

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. The reduction of body roll may reduce the need for anti roll bars. At a sufficiently high rate of movement, a suspended magnet will levitate on the metal, or vice versa with suspended metal. Earnshaw's theorem proved conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields.
