MagLev Train

We are doing a science fair project. Could you answer some questions for us?
1.How do MagLev?'s move using only magnets?

2.Why do they use electromagnets over magnets to power the MagLev trains?

3.What is the difference between Electrodynamic suspension (EDS) and Electromagnetic suspension (EMS)?

4.How fast did the first successful MagLev test run go?

5.Where was the first successful MagLev train run?

6.Are there a certain type magnets that would better to use for a MagLev
train model?

7.Do you have any pictures of models or directions of how to build a model that you could send us?

8.Do you think that MagLev trains would be an asset to the world?
