An explanation of magnetic suspension also referred to as magnetic ride control and it's benefits when used on high end vehicles. EMS magnetic levitation trains are based on this kind of levitation: The train wraps around the track, and is pulled upwards from below. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.

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. Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. 6 Halbach arrays are also well-suited to magnetic levitation and stabilisation of gyroscopes and electric motor and generator spindles.
Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. 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. Using two opposed Halbach arrays increases the field even further. 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 stable system, the opposite is needed, variations from a stable position should push it back to the target position. To calculate the amount of lift, a magnetic pressure can be defined. 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.
Magnetic levitation - Wikipedia, the free encyclopedia
Magnetic ride control uses a system known as magneto rheological technology for suspension damping. ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. In some cases the lifting force is provided by magnetic levitation, but stability is provided by a mechanical support bearing little load. 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. 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. Magnetic levitation, maglev, or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. 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. 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.

Litz wire made of wire thinner than the skin depth for the frequencies seen by the metal works much more efficiently than solid conductors. Magnetic suspension is described as the fastest reacting suspension in the world as sensors monitor the road surface up to 1000 times per second and an. 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. 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. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process.

Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. Earnshaw's theorem proved conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields.
