PURPOSE:To converge magnetic flux without loss by forming a through hole in superconductor, making magnetic flux pass the through hole from the one side of the superconductor to the other side, and leading out the flux from the other side. CONSTITUTION:A through hole is formed in the central part of superconductor 10; magnetic flux B1 of the one side (I side) of the superconductor 10 is made to pass the hole to the other side (II side); the magnetic flux B1 is converged, which is led out as the magnetic flux B2 converged on the other side. That is, suitable magnetic field generating members are arranged on the I side and the II side of the superconductor 10; the magnetic flux B1 whose section is larger than the aperture area of the through hole 11 is generated; then the greater part of the magnetic flux B1 passes the through hole 11, and reach the II side of the superconductor 10 to form the magnetic flux B2; the magnetic flux density of the flux B2 becomes higher than that of the flux B1. Thereby the magnetic flux B1 can be converged without loss. |
