Diamagnetic Levitation (1997)

  The obvious next step is to build one large enough for a person.

    Not possible. The required magnetic field increases with the size of the levitated region, and would greatly exceed limits set by strength of materials. A magnetic field that strong might also be directly harmful.

      Why not 200 frog sized fields?
      • pfdietz 5y ago
        The force is proportional to ∇ B^2, so the necessary field goes as sqrt(linear dimension of the levitation region).

    In handheld gun form?

  A.Geim got an Ig Nobel prize for the frog paper. Then got real Nobel prize for graphene research. Probably the only scientist who got both.
