Hi, after reading much interesting information on the subject I want to made a small project, the idea is to have a transparent plexiglass tube and a (diamagnetic?) material ball within the tube and to have permanent magnets outside the tube in such a way that I can suspend the ball so that it does not stick to the inner side of the tube as a ferromagnetic material ball would do in a similar situation.
The idea is to be able to move the tube back and forth or make a circle out of the tube and rotate it but the ball always maintains the same position where the external magnets are located.
I read that such levitation cannot be achieved by ordinary metals like steel balls from ball bearings because ferromagneetic materials tend to always move towards field maxima so one cannot achieve a stable position of such material but diamagnetic materials tend to move towards the field minimum.
Can you please give some advice on possible common easy to access diamagnetic materials and the arrangement of permanent magnets for such a setup to work?
thanks.
