1. The intensity of the magnetic field affects the speed of the train 2. The length of the coil, resulting in increased speed of trains 3. The diameter of the coil to make the size of the train is in motion.
1. The intensity of the magnetic field affects the speed of the train.2. The coil per length due to the speed of the train is increased.3. The diameter of the coil at the standard size to make trains are involved in the movement.
