3. Magnetic Levitation is a method by which an object is suspended with no support other than magnetic fields. Magnetic Pressure is used to counteract the effects of the gravitational acceleration and any other accelerations.. Earnshaw’s theorem proves that using only static ferromagnetism it is impossible to stably levitate against gravity, but servomechanisms, the use of diamagnetic materials, super-conduction, or systems involving eddy currents permit this to occur

4. Maglev trains are is a system of transportation that suspends, guides and propels vehicles using magnetic levitation from a very large number of magnets for lift and propulsion. This method has the potential to be faster, quieter and smoother than wheeled mass transit systems.

This method has the potential to be faster, quieter and smoother than wheeled mass transit systems. The power needed for levitation is usually not particularly large percentage of the overall consumption; most of the power used is needed to overcome air drag, as with any other high speed train The power needed for levitation is usually not particularly large percentage of the overall consumption; most of the power used is needed to overcome air drag, as with any other high speed train

5. In current electromagnetic suspension (EMS) systems, the train levitates above a steel rail while electromagnets, attached to the train, are oriented toward the rail from below. The system is typically arranged on a series of C-shaped arms, with the upper portion of the arm attached to the vehicle, and the lower inside edge containing the magnets. The rail is situated between the upper and lower edges.

8. The highest recorded speed of a Maglev train is 581 kilometers per hour (361 mph), achieved in Japan in 2003, 6 kilometers per hour (3.7 mph) faster than the conventional TGV speed record.

9. In maglev trains, there is a set of electrically powered magnets along the track that pull the train and keep all cars afloat. Thus, most energy is consumed by the track, not the train. Trains are somehow trapped in the track, which makes derailments virtually impossible. Trains are therefore technically simpler and much lighter than conventional ones. But freight operations are difficult because it would take too much electricity to keep a heavy train afloat. Track magnets set train direction and speed thus there is little chance of trains crashing into another. Since trains float, there is also no rolling resistance. Lightweight construction and absence of derailments allow safe operation at very high speeds (over 400 km/h / 250 mph).

11. Many of the active suspension techniques have a fairly narrow region of stability. Many of the active suspension techniques have a fairly narrow region of stability. The power requirements of electromagnets increase rapidly with load-bearing capacity, which also necessitates relative increases in conductor and cooling equipment mass and volume.
