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.

Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. 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. Oscillating electromagnetic fields edit A conductor can be levitated above an electromagnet (or vice versa) with an alternating current flowing through it. For a stable system, the opposite is needed, variations from a stable position should push it back to the target position. 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.

Magnetic ride control uses a system known as magneto rheological technology for suspension damping. 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. However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable. The servo controls keep it safely at a constant distance from the track. To calculate the amount of lift, a magnetic pressure can be defined.
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. 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.

Another example is the Zippe-type centrifuge where a cylinder is suspended under an attractive magnet, and stabilized by a needle bearing from below.

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

Ferrari uses them in most of their vehicles and Audi uses them in the TT and their supercar, the R8.

Either system represents examples of ElectroMagnetic Suspension (EMS). 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. 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.
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. 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.
