the Physics of Levitation


peace all

i am running into a design problem and need some help from physicists electric-engineers and others in the know ? the problem ? what i require is to levitate a small sphere such that it is relatively stable ? i think i can do this by creating an electromagnetic field ?

how do i calculate the force generated by an electromagnetic field? Is it true then for levitation that the force generated by the electromagnetic field then must counter the gravity acting on the sphere?

which is the best material to use for the sphere ? will there be a field generated in the sphere by electromagnetic induction?? i don?t even know if that is the right term ? but how will this effect the levitation ? is this physically possible ? if so how ? if i am just dreaming ? someone wake me up!!

thanks
peace out

Talk to my friend Ziad1. I know he did this as his senior year project. I know because I had to hear the story at least thirty thousand times. Nerd power!
