## Main Question or Discussion Point

Hi, I have a few questions regarding magnetic levitation achieved by using alternating current to induce eddy current on a non-ferromagnetic conductor plate to provide the levitation force.

1. Can it be stabilized? If yes, in what ways?

2. Are there any equations/formulae or ways to calculate the levitation force provided by eddy current in this case? Which physics laws and equations should I apply in this case? (Except Faraday's and Lenz's law)

3. Is there a direct relationship between the frequency of alternating current and levitating force?

I've looked up the Internet for the whole day but still could not find an answer, your help is appreciated.

Also, I'm planning to use this as my extended essay topic, is this appropriate? (Extended essay is a 4000-word research paper that has to be completed in the IB Diploma)
