SUMMARY

The discussion centers on the feasibility of frog levitation through diamagnetism, requiring a magnetic field of approximately 10 Tesla. Participants express skepticism based on prior experiences with 3 Tesla fields, noting limited effects on non-magnetic materials. The conversation references significant research and papers, including those by Andre Geim, who won both an Ig Nobel Prize and a Nobel Prize for related work. The levitation phenomenon is attributed to the principles of diamagnetism, which can affect certain materials under strong magnetic fields.

PREREQUISITES
  • Understanding of diamagnetism and its principles
  • Familiarity with magnetic field strengths, particularly 3 Tesla and 10 Tesla
  • Knowledge of materials science, especially regarding magnetic and non-magnetic materials
  • Awareness of notable scientific contributions, such as those by Andre Geim
NEXT STEPS
  • Research the principles of diamagnetism in detail
  • Explore the effects of strong magnetic fields on various materials
  • Study the experiments conducted by Andre Geim related to levitation
  • Investigate the implications of magnetic levitation in practical applications
USEFUL FOR

Physicists, materials scientists, educators, and anyone interested in the applications of magnetic fields and levitation phenomena.

I found a website claiming that a frog can levitate.
A "large magnetic field" of the order of 10 Tesla is all that would be needed.
And the effect would be a consequence of diamagnetism.

I am a little bit skeptic about that.
I was familiar, long ago with large devices where magnetic field of the order of 3 Tesla were used.
I had never heard of big effects on "non-magnetic" materials (like wood for example).

What do you think about that?
Could you give some order of magnitudes and explain what would be the effect of large magnetic fields on diamagnetic substance?

Thanks

I suppose if you were to feed the frog enough iron filings!

(Reminds me of Mark Twain's "The Celebrated Jumping Frog of Calaveras County".)
