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. For the form of transportation, see. 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. La mayora tienen espacio detrs para los cables, por lo que tambin puedes colocar en ellas dispositivos mientras se cargan. These kinds of systems typically show an inherent stability, although extra damping is sometimes required. 3 For example, the simplest example of lift with two simple dipole magnets repelling is highly unstable, since the top magnet can slide sideways, or flip over, and it turns out that no configuration of magnets can produce stability.

Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable. 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.

Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable.

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. 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.
Magnetic levitation is used for maglev trains, contactless melting, magnetic bearings and for product display purposes. 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. For the form of transportation, see.

Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. 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. 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 force is used to counteract the effects of the gravitational acceleration and any other accelerations. 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.

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. The net effect is to more than triple the lift force. 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.
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. 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. To calculate the amount of lift, a magnetic pressure can be defined. 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. 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.
