Undergrad Can Electromagnetic Levitation Make an Entire Apparatus Go Skyward?

[Willb1998]

Hi I'm new I had the idea that possibly diamagnetism, levitation and electromagnetism could be linked for example I know that a magnet can be levitated between 2 pieces of bismuth. I'm not good with math nor electricity but do you think if something being repulsed like a bismuth plate was bolted to a base with all thread over an electromagnet would the whole apparatus go skyward? Most people think of a stationary base and something like a train being levitated above. Just wondering if the whole thing would go upwards or levitate including the base.

No. It would levitate up to the point were either a) gravity will win b) the diamagnetic force saturates.

Interesting at 1:16 you can see a large aluminum cylinder hopping upwards and levitating for probably half a second on its way back down.
