ort, without lubrication, thus eliminating friction. All practical magnetic levitation systems are inherently open-loop unstable and rely on feedback control for producing the desired levitation action.The \maglev" experiment is a magnetic ball suspension system which is used to levitate a steel ball in air by the
Where the current in the coil of the electromagnet is, is the gravitational constant, is the magnetic force constant and is the mass of the object. The levitator consists of a magnet that create a magnetic field and electromagnets that control that magnetic field.
The interaction of the (magnetic field from) the induced currents and the original permanent magnetic field produce a repulsion force which levitates the magnet. These fundamentals are the basis of several different configurations of Maglev systems. The figure below shows six Maglev arrangements. Five of the arrangements rely on repulsive forces.
With some practice and small but precise movements, the magnets should be able to levitate. Tip: If the magnet tries to flip over such that the mark on the magnets is pointing away from the inductor, the magnetic fields are the same and repelling each other.
Among useful usages of magnetic levitation technologies, the most important usage is in operation of magnetically levitated trains. Maglev trains are undoubtedly the most advanced vehicles currently available to railway industries. Maglev is the first fundamental innovation in the field of railroad technology since the invention of the railroad.
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.
