How to build a magnetic levitator for a school physics club

[astro_chara]

Hi, recently I've been trying to think of a few ideas for my high school physics/astronomy club to build, and have heard that a magnetic leviator is completely doable.

Are there any tips out there for building one? Materials, circuits, etc would help a whole lot.

Thanks.

You will get better and more helpful answers if you can ask more narrowly focused questions. Try googling for "magnetic levitation project", see what you find, and if you then have more specific questions you can try asking them here.
