PURPOSE: To provide an internal magnetic field measuring method of supercon ductor structure, magnetic shield characteristic measuring method of superconduc tor, and internal magnetic field measuring device of superconductor structure in which the internal magnetic field to AC magnetic field and DC magnetic field and its magnetic shield characteristic can be relatively easily measured. ;CONSTITUTION: A magnetic field detecting coil 4 is arranged in the inner part of a superconductor structure 1, and the signal having a frequency synchronized to vibrating frequency is taken out and detected from the electric signals generated in the magnetic field detecting coil 4 when the superconductor structure 1 or the magnetic field detecting coil 4 is vibrated. Thus, the internal magnetic field of the superconductor 1 to AC magnetic field and DC magnetic field and its magnetic shield characteristic can be relatively easily measured.;COPYRIGHT: (C)1993,JPO&Japio
