Levitation. Maglev trains have no contacts with the rails while they move forward. They are levitated on the guide-way with the help of magnetic forces. Levitation is the process by which an object is suspended against gravity in a stable position without any physical contact.
The train, however, cannot carry an unlimited amount of weight; the magnets can only supply a limited amount of force depending on how strong they are. Eventually, if you add too much weight to the train, it will sink down and touch the tracks. In this physics science project, you will build your own maglev train model and see how much weight it can hold before sinking to the tracks.
