Abstract:
1. An apparatus for levitating a diamagnetic material, said magnet comprising: a first superconducting coil having a central axis, said first coil producing a magnetic field when energized with current; a second superconducting coil positioned concentrically within the first coil, said second coil having a central axis generally parallel to the central axis of the first coil and producing a magnetic field when energized with current; and a third superconducting coil positioned concentrically within the second coil, said third coil having a central axis generally parallel to the central axes of the first and second coils and producing a magnetic field when energized with current and said third coil defining a bore of the magnet, said magnetic fields of the first, second and third coils combining to produce an operational magnetic field for levitating the diamagnetic material inside said bore.
