PROBLEM TO BE SOLVED: To achieve increase in the volume of a microgravity area by a simple configuration, in a magnetic force field generator for generating a microgravity area by disposing ferromagnetic bodies or rings or discs of permanent magnet at positions coaxial with the central axis of hollow interior of a superconductive magnet.SOLUTION: At the positions described above, three rings are disposed while being staggered in the vertical direction. A uniform and strong magnetic field is thereby generated in a doughnut-shaped area surrounded by these rings, and a microgravity area can be obtained there. In a conventional configuration, only a localized microgravity area is obtained around the central axis, but the capacity can be increased according to the invention because of the doughnut-shaped microgravity area. |
