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. Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. Using two opposed Halbach arrays increases the field even further. Earnshaw's theorem proved conclusively that it is not possible to levitate stably using only static, macroscopic, paramagnetic fields. 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 net effect is to more than triple the lift force. 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. 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.

Again, litz wire gives the best results. La mayora tienen espacio detrs para los cables, por lo que tambin puedes colocar en ellas dispositivos mientras se cargan. However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved.

Magnetic force is used to counteract the effects of the gravitational acceleration and any other accelerations. The viscosity of the polymer liquid can be changed to an almost solid state similar to plastic or rubber in composition. Another geometry is where the magnets are attracted, but constrained from touching by a tensile member, such as a string or cable. Conductors can have a relative permeability to alternating magnetic fields of below one, so some configurations using simple AC driven electromagnets are self stable.

Mechanical constraint (pseudo-levitation) edit With a small amount of mechanical constraint for stability, achieving pseudo-levitation is a relatively straightforward process. Such a simple system is not very robust; far more effective control systems exist, but this illustrates the basic idea. This causes any regular conductor to behave like a diamagnet, due to the eddy currents generated in the conductor.

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. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. 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. 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. 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. An explanation of magnetic suspension also referred to as magnetic ride control and it's benefits when used on high end vehicles.

The servo controls keep it safely at a constant distance from the track. 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. Magnetic ride control uses a system known as magneto rheological technology for suspension damping. 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. Magnetic suspension reduces vibrations, bouncing, noise and body roll very effectively on all road surfaces and at any speed that the vehicle could travel. 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. However, servomechanisms, the use of diamagnetic materials, superconduction, or systems involving eddy currents allow stability to be achieved. 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. Litz wire made of wire thinner than the skin depth for the frequencies seen by the metal works much more efficiently than solid conductors.

ECU can make variations within a few milliseconds resulting in the possibility of multiple damping variations being made in a second. Other companies, such as Ferrari and Audi are also known to use magnetic suspension in their vehicles. Damping of motion is done in a number of ways: external mechanical damping (in the support such as dashpots, air drag etc. Using two opposed Halbach arrays increases the field even further. 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. 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.
