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.
Best Answer: A maglev train is powered by electro magnets. The lightweight design heps the train achieve high speeds. Instead of rails it operates on an electromagnetic field called a guide way. The train's conductor can control the force of the magnets to change speeds. These trains cannot stop easily which has a large affect on crashes. Those are the basics of a maglev.
