ABSTRACT:
A device is provided for suspending an external load by means of a magnetic field and a superconductor. The superconductor is supported in a magnetic field which penetrates the superconductor. A magnet is suspended below the superconductor and oriented so that its magnetic moment is aligned parallel to the magnetic field. The magnet is provided with a coupling means so that it can be coupled to an external load. Either a vertical or a horizontal magnetic field can be used. In one embodiment, the load-carrying member is a composite material suspended from a supported magnet. The composite consists of a superconducting phase and an attractive phase comprising either a magnet, a ferromagnetic material, or a paramagnetic material. In another embodiment, a device for concentrating flux is provided by placing a superconductor between the source of the magnetic field and the position in which the concentrated flux is desired.
