i want ask guys if it possible to do controllable maglev train and what i need basically

 

Of course its possible. Nothing is impossible as long as you're willing to build it.

read this link :

And you will get the big idea to get started.

It said that for this system you will need :

• A large electrical power source
• Metal coils lining a guideway or track
• Large guidance magnets attached to the underside of the train

In short, a lot of electromagnetics.

Good luck !

 

Here's a maglev design that's totally passive.

That's a cool design. We use Halbach arrays to confine and focus ion beam surface charge on wafers for neutralization with a Xenon plasma. The problem with this method of levitation Earnshaws_theorem is that it requires relatively high motion (energy) to be stable in a simple configuration without mechanical constraint. To achieve stable levitation at 1 to 2 kilometers an hour must require some very strong magnets and a complex track coils but it should be possible to build a simple version using a fast moving 'car' with a cable constrain on the track.
