Filmed 1991-1996, 7 of 15 methods of levitating an object known to the author John Iwaszko, edited from the video Antigravity the reality made in 1996. The antigravity method shown in this edit, at the time was originally classified as 6th Method-Superconductor/Magnetic Meissner Effect which has now been reclassified by the author as, Method 7 Dia-magnetic Superconducting (Meissner), Group IIB(i). Superconductors don't allow magnetic fields to penetrate, so a magnet placed on top of superconductor will levitate. The superconductor in this demonstration is a substance known as YBCO (yttrium barium copper oxide), and it superconducts at a temperature high enough (77K) that liquid nitrogen can be used to make it reach its superconducting temperature. Superconductors may be considered perfect diamagnets, completely expelling magnetic fields due to the Meissner effect. The levitation of the magnet is stabilized due to flux pinning within the superconductor. This principle is exploited by EDS (electrodynamic suspension) magnetic levitation trains, superconducting bearings, flywheels, etc.
In trains where the weight of the large electromagnet is a major design issue (a very strong magnetic field is required to levitate a massive train) superconductors are sometimes proposed for use for the electromagnet, since they can produce a stronger magnetic field for the same weight.
