The trial was the trial results, it appears that the 2.3 magnetic RADIUS, number of coils of wire, Seoul lane of Android, the less magnetic field in the coil is less. Thus resulting in a low-speed or train doesn't move.
2.3 The results of the experiment showed that the radius of the magnetic coil of wire, increasing the number of solenoid less and the intensity of the magnetic field in winding down. As a result, trains slow or not moving at all.
From the experiment the experimental results showed 2.3 radius of more number of coil of magnetic wire sole (ด์น้ less and the intensity of the magnetic field in the coil. Therefore, the train has low speed or move.
