Spinning magnets? By "support" you mean as a base or the globe?.. Because I think the globe is supposed to be static...
I guess we'll stick to the feedback systems, they require some soldering and more calculations but seem to provide more stability.
Thank you for the reply!
Hello,
I am a student and this semester I am doing a project in Experimental Physics class. We plan to make a levitating globe! We have already researched on methods of overcoming Earnshaw's theorem and chose two:
1) Using eddy currents to stabilize an object (conductor)
More or less...
