How Can Electromagnets Revolutionize Future Magnetic Cars?

[strachi]

I'm a first year undergraduate student in UK and i got to make a poster which will be about a future car.
I thought about magnetic cars but i need some advise on how the whole thing will work.
I mean i thought about making the cars out of iron and use permanent magnets as roads but that's not a really good idea.
How about electromagnets? How can I put all that theory about induced emf into practice for this assignment
can you please explain in detail how it can work?

strachi -- you are referring to magnetic levitation, or maglev. Here's a good starting resource for your research. Have fun!
