Discussion Overview

The discussion revolves around the concept of electromagnetic levitation, specifically exploring whether an entire apparatus, including its base, can be made to levitate using diamagnetism and electromagnetism. Participants consider the implications of these forces in a practical setup.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • One participant proposes that if a bismuth plate is bolted to a base over an electromagnet, the entire apparatus could potentially levitate, challenging the common notion of stationary bases.
  • Another participant counters this idea, stating that levitation would only occur until either gravity overcomes the diamagnetic force or the diamagnetic force reaches saturation.
  • A later reply mentions an observation of an aluminum cylinder levitating briefly, suggesting practical examples of levitation phenomena.

Areas of Agreement / Disagreement

Participants express differing views on whether the entire apparatus can levitate, with some supporting the idea and others asserting limitations based on gravitational and force saturation factors. The discussion remains unresolved regarding the feasibility of the proposed concept.

Contextual Notes

Participants do not provide detailed mathematical analysis or definitions, leaving assumptions about the forces involved and their interactions unspecified.

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.
