Question

3. A maglev (magnetic levitation) train is lifted above the train track by magnetic repulsion when it is moving, Why is it that a maglev train can move much faster than a normal train?​

Answer 1

Answer:

It is the interaction between the magnetic field created by electromagnets at the bottom of the train and the magnetic field resulting from the arrangement of rails that the train raises a little above and move forward fast. since no contact is there between the train and the rails there exists no friction.
