DIAMAGNETIC LEVITATION: can a frog really levitate?

AI Thread Summary
A website claims that frogs can levitate using a magnetic field of around 10 Tesla due to diamagnetism. Skepticism arises from past experiences with 3 Tesla fields, which did not significantly affect non-magnetic materials. The discussion seeks clarification on the effects of large magnetic fields on diamagnetic substances and their order of magnitude. References to research papers and notable achievements, such as an Ignobel prize awarded for related work, highlight the scientific interest in magnetic levitation. The conversation reflects curiosity about the feasibility of levitating frogs and the underlying physics involved.

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".)
