Building powerful magnetic levitation device

[Anoop Koushik]

I want to have a powerful magnetic levitation device as an attraction for college fest and also as my first big project!
So I need to know how to start with it.
I need to workout with all theory parts before I start building it !
Where to start from?

You'll need one of those 5 concepts, all have some problems:

• Superconductors - cooling and cryogenics issues
• Active electronic stabilisation - not easy to realize
• Rotation (Levitron-style) - can be hard to balance out if you want to do it on your own
• Really strong magnets and diamagnetic materials (like the levitating frogs) - I doubt you'll reach the required magnetic field strength
• some support structure with contact - probably not what you want

You might want to look at a Halbach array for a short levitation track.

I don't suppose you wanted a make a demonstration like this one:

I want to build something similar to CLM 1.5 !
