MAGNETIC FIELD OF TECHNOLOGY ON FAST TRAINS

Flying train, known as magnetically Levitated Train (Maglev Train) is only going to drift as high as several inches (+ -1.0 cm) above the railroad tracks. We start with the name: magnetically Levitated Train.
The train can be lifted due to the magnetic forces. We know that magnets have two poles, the North (U) and South (S). We also know that the North Pole and South poles always attract, while similar poles (North or South to North with the South) is always repulsive. The basic principle applied is simple to run and 'fly'

In the figure ranks of magnets along the walls and along the train (the letters U shows the North Pole, and S indicates the South Polar). Along the magnetic line of this wall is produced by alternating electric current from the nearest stations. North Pole (U) on the front train car pulled by the South Pole and North Pole was rejected by the track wall. The same thing happened on the other side of the train. In the figure, green arrow shows the attractive force between the North Pole and South that attract Figure 2.a advanced train. Small blue arrows indicate repulsion between similar poles (North by North, South, with the South). Attraction and repulsion that work together it makes the train move forward smoothly.

The principle Style attraction and repulsion magnetic poles! In Figure 2-B we see the magnets on the track wall. This magnet is produced by electromagnetic induction caused by the train.When the position of the train a few centimeters below the magnetic center of this wall, then the South pole will pull the wall rail to the top and the north pole will drive the train also and above.Tensile force and thrust it makes trains floating, not touching the rails at all. The walls that enclose the track this train not only serves to pull and push the train to move forward and lift the train so that it can float. There is one other function that is not less important, namely to control the speed of the train (guidance).
The point is that the train is never out of line and stay in the middle of the track every time. The principle of magnetic re-used as a controller. When the train wobbling to the left, the train movement has resulted in the coil of wire left and right wall into a magnet. Magnets on the left wall and right wall has cultivated the same pole, such as the North Pole. For example, the rail cars are faced with a wall on the left side has the North Pole as well, and train carriages are faced with a wall on the right side has a South pole. On the left side will happen repelling between the North pole of the wall and the North Pole train car. On the right side of attraction occurs between the North pole South pole walls and trains.
These forces will return the cart before the shaky position. Similarly, if a train wobbling to the right, the train will be restored to its original position by the force of this magnet. So the magnetic force so that it will maintain the trains stay on the path (stable in the middle of the track), will not be out of line.
If there is no friction means no obstacle (just have to overcome air resistance) so the train can glide smoothly with very high speed! To reduce air resistance design of the train intentionally made so that the front part shaped like a dolphin's snout.
