DIAMAGNETIC LEVITATION: can a frog really levitate?

    I found a web site 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".)
